1 mistake in Birthday Cake
Starring: Vic Morrow, Jack Hogan, Pierre Jalbert, Rick Jason
Braddock: Don't just stand there sucking on a prune pit, get these men some water.
Trivia: Actor Vic Morrow used a non-firing wooden replica of a Tompson submachine gun due to its lighter weight, thus being easier to carry. He used a heavier blank-firing model when it was required to be fired.
