E.T. the Extra-Terrestrial (1982)

Continuity mistake: In the exterior front shots of Elliott's house there are some significant changes to the landscape in different shots. For instance, the two lampposts at the bottom of the driveway change to an entirely different style in some shots, and the huge garden boulders repeatedly vanish and reappear. Also, note when Michael takes off on Elliott's bike to go search for ET, the in-ground lamppost that should be beside the mailbox has vanished, but it reappears when all the government agents are setting things up outside the house.

Elliot: Okay, he's a man from outer space, and we're taking him to his spaceship.
Greg: Well, can't he just beam up?
Elliot: This is reality, Greg.

Trivia: When the children go out on Halloween night, they pass other children dressed up. One that they pass is dressed as Yoda from Star Wars, and at this point the music plays Yoda's theme from Star Wars. John Williams wrote the music for both films.

Question: When Elliott, Mike and Mike's friends are escaping from the agents on their bikes, are the actors' stunt doubles adults or teenagers? Asking because I've heard of teenagers being stunt performers in movies.
