The Truman Show

Ed Harris and Jim Carrey never met during filming.

When Marlon is restocking the candy bars in one of the vending machines, he works on filling up one of the rows. The scene switches to Truman talking with Marlon, and when the scene switches back to the vending machine, the row that Marlon had filled in is empty. However, earlier in that scene Marlon can be seen removing two candy bars when Truman is not looking, then stocking them back into the machine. It is obvious Marlon is just acting busy by moving candy bars back and forth, thus killing time and keeping Truman stationary so the important discussion can unfold on camera.

In the end credits, the cast is divided between Truman's World, Christof's World and The Viewers

A lot more pseudo-documentary footage on the making of the fictional Truman Show was shot but not used in the theatrical version. Only some short segments have been included in the released film, in the pre-credits sequence. Segments of this outtake footage, featuring Meryl Burbank and Marlon being interviewed and talking about their roles on the show and their personal lives, have been included in some airline versions, presumably to pad the running times.
