Steven Spielberg was displeased to learn that Universal used footage from his movie Duel (1971) in this episode. Unable to sue on the matter (due to the studio's ownership of both the film and Hulk series), he insisted that all his future contracts list a clause designed to protect his movies from being used as stock footage.
During the pre-credits trailer, when David jumps into Joanie's truck he says "Mind if I get in?", whereas, in the main programme, he says "What are you doing?"
One of the few episodes to end on an upbeat note for David. The end credits also play over a still of the uplifting scene instead of the usual shot of David either walking away into uncertainty or hitchhiking.
David's 2nd Hulk-out is similar to that of a previous episode, '747', where David is in control of a vehicle while he changes.
The $10 that Joanie offers David to deliver the message comes out to $48.20 in 2024 adjusted for inflation.
