Goofs

When Jim wakes Aurora up his hair is very messy and unevenly cut because he cut it himself. In the next scene within hours at the most, possibly minutes, his hair is cut normally.

The shrapnel wound Aurora receives in her upper left arm while trying to vent the hot gas disappears during later scenes when that portion of her arm is visible.

Jim takes the I.D. bracelet from Gus twice.

Early in the film it's announced that the passengers will be awake well before the ship arrives at Homestead II so they can enjoy the ship's facilities on the slow approach. Yet when you see the ship in close proximity to Homestead II at the end it's clear that Captain and crew have only just been woken up because they look surprised when they discover the changes made by Jim and Aurora.

When Aurora undresses for the spacewalk, she tosses her dress past Jim's left boot. In the next scene, the dress is coming past Jim's right boot.

When Aurora is trapped in the water bubble, she appears to be unable to swim out of it. Even in zero gravity Newtons third law of action equaling reaction still applies. Pushing water backwards (through swimming movements) would easily push her forward to the surface and out of the bubble.

When the ship loses gravity this happens instantly. However, judging from the external design of the ship gravity is achieved by rotating the ship around its axis. It would be impossible for the ship to stop rotating completely in an instant as another reverse force should be applied, losing power would still have the ship rotating and thus providing gravity. Even if ship's computer would behave erratically and decide to reverse the spin of the ship, this will most likely not happen instantly and therefore gravity would be lost gradually.

The airlock from which Jim (first) and then Jim and Aurora (later) exit for their spacewalks is in one of the rotating pods; however, when the spacewalkers jump off the pod and spin out to the extent of their tethers, the stars are stationary.

Supposedly the ship reaches the star Arcturus 31 - 32 years into the trip - they were both awake so at minimum his 30 years plus the year before he woke her but before Gus woke up after another year. Arcturus is 36.7 light years from earth. At half light speed they would only have traveled 16 light years. Nowhere near Arcturus. This hold true even if we assume unknown acceleration/deceleration. 30 years into the flight they are already doing 50% light speed.

The Avalon's journey is scheduled to take 120 years, and this is regarded as a constant throughout the film. Since the ship is traveling at half of light speed, relativity will be a factor, and time will pass slower on board ship. One hundred and twenty years of ship time would equate to about 138 years on Earth or Homestead 2.

When Jim does his first space walk, he cries and tears roll down his face. In zero-gravity, the tears would not roll down his face, they would float out of his eyes. But since he's attached to a rotating ship - much like a rock in a slingshot being twirled above one's head - he's not in a zero-gravity environment. The tear would "fall" away from the center of rotation (directly toward the visor).

The ship has spare parts for everything, but apparently doesn't have the ability to wake up anybody to install them when necessary. If it's going to carry them anyway, it wouldn't be that much more difficult to actually have them installed and functional as automatically redundant backups that would switch in when necessary without human intervention. The spare parts are presumably in addition to any built in redundancy; such as the ability of the engine control computer to commandeer the processing power of other devices.

When the ship approaches Arcturus, a message informs passengers that they might be interested to watch the slingshot. Since the entire crew and passengers are supposed to be asleep until destination, there is absolutely no reason why such a message would have been designed, recorded or played.

However as we already seen, everything on the ship reacts to them, the bartender, computer, information points, the waiters in the restaurants and so on. It is therefore plausible that the slingshot information is being played because of their presence.

At the end of the film, when the Avalon is seen approaching Homestead-II, the ship is seen to have its engines facing away from the planet, but still operating. Assuming its course included a long stay, the engines would have need to be turned in the direction of travel - not only for reducing speed for safe orbital-insertion, but about halfway through the voyage, as as much time would need to be taken to decelerate as was taken accelerating.

But if its course was to slingshot around Homestead II's star without planetary orbit, it might need to continue thrusting in the direction shown.

A "slingshot" around a star is caused by the ship and its contents "falling" towards it, so there is very little differential force on the ship and passengers. It should not be confused with driving a car around a banked track, or a fast turn in a aircraft; where the external force acts only on the vehicle.

The medical auto diagnostic scanner shows Gus to have 612 disorders, however in a close up to the found disorders, it shows much less disorders that are duplicated.

The ship momentarily loses gravity as Aurora and Jim are running through the main mall towards the end of the film. They then enter the bar to deactivate Arthur. The bar shows no signs of the gravity loss. All the bottles, bar stools, and glasses are still in place. Arthur could not have had time to clean up.

While Jim tries to explain to Aurora on the ship P.A system why he woke her, he is watching her jog on the ship CCTV. She can be seen running on a bank of screens next to Jim, each screen showing the view from a number of different cameras. But when she stops at a wall and turns, there is a delay between the monitors: Aurora starts running on the left and right videos first, then running on the center one.

Error In Visual effects. When Aurora is asking why Jim was not a gold class passenger during breakfast in the cafeteria, in the background to the right of the screen, you'll notice that there are several inoperative vending machines.

Things do not instantly freeze in space as shown. Any water vapor not taken out with the air in Jim's suit would dissolve into a cloud of very fine crystals. It couldn't frost up his visor in the way shown.

When Jim rushes to his room in a panicked state after just waking up Aurora, he sits on the bed and a moth or some kind of fly can be seen flying behind his right shoulder.

It wouldn't be possible for the passengers to view the star they pass by for more than an instant as the ship is rotating to simulate gravity which would quickly turn them away from the view.

In reality, swarms of rocks as depicted in this and other space disaster films don't exist, as gravity would consolidate them given a billion years or more, particularly with that one big rock in the middle. Even the asteroid belt in our solar system is pretty sparse. We've sent several probes outwards through the asteroid belt already, and none of them had to dodge anything.

When Aurora questions Jim about why he chose to travel to Homestead II, she casually debates the 'altruistic' motives of the Homestead Corporation for sending passengers to a distant star system at a reduced rate. She mentions how 'indentured service' is a component of the fare, in which each passenger must pay 20% of whatever they earn for the rest of their life to the corporation. Mention is also made of how the company has made 'quadrillions of dollars' from interstellar colonial activity, a vital part of which includes the indentured service of colonists on far-flung star systems. The nagging question is HOW the corporation can tangibly REALIZE a return on their investment - in a reasonable frame of time, to the satisfaction of their investors/shareholders, and for the benefit of Earth-bound investors within their own lifetime, no less - when just a one-way trip to these systems is on the order of multiple decades. Furthermore, a return trip is well in excess of a century (if Homestead II is a typical example on how far viable, habitable systems are from our own solar system) and Aurora suggests she, herself, hoped to be the FIRST person to make a round trip to the stars and back (suggesting a round trip - and time on the planet - of at least 240 years). Even if the very function of economics has changed radically in this particular future, the basic principal of give-and-take and something-for-something just doesn't even REMOTELY flesh itself out with the Homestead Corporation model of indentured service for Earth-bound investors (or investors on star systems other than Homestead II).

When Jim (Chris Pratt) is using a joystick to guide the messenger robot to Aurora with his dating invitation, the joystick is a real life USB gaming joystick, the Logitech Extreme 3D Pro. In one camera angle, a piece of black tape or black paint is covering part of the right side of the joystick base to cover-up the words "Extreme 3D Pro" since, presumably, future multi-trillion dollar star ship would not use a $39 gaming stick decades from now.

While Jim tries to explain to Aurora on the ship P.A system why he woke her, he is watching her jog on the ship CCTV. She can be seen running on a bank of screens next to Jim, each screen showing the view from a number of different cameras.Watch carefully and her stopping at a wall turning to run back do not match up on all the cameras.

There would be no way for the company to receive "updates" of what occurred to the missions that it sent to Homestead II. The trip is stated as taking 120 years. That would mean that each flight sent would arrive potentially several decades after the last member of each launch crew was deceased. Even if telemetry sent constantly in-flight , it would still take decades to return to Earth, if the signal even made it to its destination. This also means that any information that the company did have about Homestead II would be woefully out of date. At light speed, transmissions sent from the planet would take decades to arrive at Earth; waiting for verbal confirmations would take more than 100 years for each one. There would never be any successful means for the company to have "real time" knowledge of the ships, nor their voyages making the information offered by the computer and the characters either falsehoods or simple speculation.

After collecting diagnostic data computer is able to show hibernation's pad malfunction, yet there is no indication of a hull breach. It should be easily detected. And detecting such accidents should be one of the main concerns when thinking about ship's safety.

The ship is able to automatically repair most of the malfunctions, there are plenty of robots on board. With available technology it should be easy to auto-repair the hull breach.

When discussing hibernation pods, Aurora says that the company has made thousands of interstellar flights without a single hibernation pod malfunction. Earlier, when Jim tried to send a message back to Earth, he is told by the computer that it would take around 80 years for a round-trip message. The home company on Earth would therefore have needed hundreds of years to communicate enough with thousands of interstellar flights to not only verify that they reached their destination, but also how well everything functioned. Not only that, but that time is expressed only as the time relative to the space travelers, but much more time passes on Earth relative to the space travelers, according to Einstein's Theory of Relativity, since they are traveling at half the speed of light (or at least they are in the time frame during the voyage that the movie takes place, but since it's not halfway yet and the ship is still accelerating, it must reach even faster speeds).

It doesn't make sense that much of the ship's computers, such as the android bartender Arthur and the cleaning droids, would be operating during hibernation, as there are no one to serve drinks to or clean up after. Also, the ship's computers display and voice messages despite there being nobody to see or hear them. All of this, and more, has to be a significant waste of energy, which a 120 year long journey should not be able to afford.

At 41:59, Aurora subtly derides Jim for believing "Homestead Company propaganda" after he says his motives for emigrating are adventure, usefulness, and a fresh start in life. Yet earlier in the film (25:51), when Jim is watching a video of her being interviewed about her decision to go on this trip, her reasons are not very different than Jim's.
