Corrected entry: When Felix enters the Flanders Hotel at the beginning and asks for a higher room, the man behind the counter puts his pizza on the counter, but in the next shot, it's in his hand again.
The Odd Couple (1968)
1 corrected entry
Directed by: Gene Saks
Starring: Walter Matthau, Jack Lemmon, John Fiedler, Herb Edelman
Revealing mistake: When Walther Matthau is making sandwiches for his poker pals (during the movie's first poker game), Matthau drops a slice of bread on the kitchen floor. If you look at his hand, you'll see that he flicks his thumb to make the slice of bread fall.
Oscar Madison: I can't take it anymore, Felix, I'm cracking up. Everything you do irritates me. And when you're not here, the things I know you're gonna do when you come in irritate me. You leave me little notes on my pillow. Told you 158 times I can't stand little notes on my pillow. "We're all out of cornflakes. F.U." Took me three hours to figure out F.U. was Felix Ungar.
Correction: The man puts his pizza on the counter and later on, while he is talking, he picks it up again.
