Multiplicity (1996)

Continuity mistake: When Michael Keaton is talking to his wife he picks up Froot Loops, then a second later he picks up Cheerios.

Doug #2: [seeing Doug #1] Is that it?
Dr. Leeds: No. I'm afraid you're it.
Doug #2: What do you mean? I can't be it. You mean, you think I'm the clone?
Dr. Leeds: That's right.
Doug #2: I can't be the clone, I'm me. He's gotta be the clone.
Doug #1: No, see I'm, I'm me. I'm me. I'm me, right?

Trivia: When Three calls Doug's job to say that Doug is sick, on the day of a building inspection, Michael Keaton uses the same voice that he did in the movie "Beetlejuice." The building inspector is played by Glenn Shadix, who was also in the movie "Beetlejuice."
