Trivia: The two 'disc jockeys' in the soundbooth of the 'End of Line' club are actually Daft Punk, the French group that created the movie's soundtrack.
Trivia: In the first film, the street sign outside Flynn's Arcade indicates it's on Watseka St. In the second film, the street sign in front indicates the arcade is on Mead St. Also, the surrounding neighborhood seems to have undergone some redevelopment. This isn't really a mistake since a lot can happen in 28 years.
Trivia: After Sam hacks into the back door of ENCOM he comments: "Now that's a big door." Kevin made the same comment when he hacked into ENCOM's back door in the first movie.
Trivia: Two references to "The Black Hole", another Disney movie, can be seen in the film. There is a poster for "The Black Hole" in the bedroom of Sam Flynn in 1989 and an action figure of the Old B.O.B. robot is on his shelf next to the Tron action figures.
Chosen answer: He doesn't know Clu is dead. And a little prudence never hurts. Flynn knows Clu and clearly it was entirely possible that Clu was still alive. If they all got back to the portal, it made no difference. If Clu showed up to stop them, Flynn knew what he had to do and needed to make sure that Sam had his disc to get out.
