Goofs

In a helicopter rescue scene, the Coastguard S92 helicopter then changes into a much smaller AW 189 helicopter.

At the end of the film, Danny parks a brand new Range Rover on the beach, when the tide comes in the Range Rover is a much older model.

Near the end of the movie, after Danny parks his Range Rover just off the concrete on a wide beach, he returns to a beach at which the water has not risen to the level the Range Rover was originally parked and one that is not nearly as wide as the one on which he parked.

After the quiz night, Danny asks her "Who was the first artist to have a posthumous #1 in the UK?" she answers straight away - "Otis Redding - Sitting on the Dock of the Bay, in 1968." Well, this is wrong, Otis wasn't the first, second or indeed third. The first one was Buddy Holly - It Doesn't Matter Anymore (1959), second was Eddie Cochrane - Three Steps to Heaven (1960), third was Jim Reeves - Distant Drums (1965).

However, this isn't stated to be the factually correct answer within the film. It's just one character's answer. Thw character guessing the wrong answer is different from it being factually incorrect.

When Danny finds his Range Rover partially submerged. It's suggested that the engine will be damaged. But Range Rover's are pretty well protected against water ingress. Even though many of their owners (including Danny) don't use them to their full capabilities, they're a very capable off road vehicle. It's very likely that once the tide went out it would have been possible to start it and drive it.

However, this is stated as the personal opinion of a single character, who's been drinking. There's also a history of characters winding each other up in the film. It's quite possible he was joking or simply wrong. It is not a factual error.

At the end Danny parks his car with lots of other cars on the wharf - when the tide comes in his is the only car there - what happened to all the others?? Quite simply, the other car's owners got in them and moved them before the tide came in.

When the group sings "What Shall We Do With The Drunken Sailor" in a pub, a wide shot outside the pub at the start of the scene features a bus passing by featuring an advert for "The Grinch" (2018), despite the fact the film is set in 2010.

When the group goes to London, New Routemasters are visible on the streets; these did not enter service until early 2012, and the film is set in late 2010.

Scenes show journeys to/from London crossing the A38 Tamar Bridge en-route to Port Issac. This is not the logical route for this journey as the A30 over Bodmin Moor is the direct route.

However, this isn't a plot hole. The plot of the film isn't broken because a character didn't take the direct route. It's still a valid, if unexplained, route.

Early on in the film when Danny is left behind and is trying to get mobile reception to phone his colleagues, a female villager tells him the only place to get reception in the village is by standing on the sea wall. However, throughout the film he regularly makes and receives calls with his mobile throughout the village such as at the church and at the B&B.

However that isn't what the female villagers says to him. She says, "the only place you'll get reception down here is on the sea wall." By "down here" she means by the seafront, where they are stood at the time, not the entire village. It can be assumed there is still reception in other parts of the village, such as the church and the B&B.

Danny agrees with young Tamsyn that Canute was an idiot for trying to stop the sea, but according to legend the king was rebuking his flattering courtiers.

At the quiz night, Danny disagrees with Alwyn that the artist who has had the most weeks at the top of the UK Hit Parade ever is not Elvis Presley, but the Beatles - who would either be referred to as a band, a pop group, or four artists.
