MICHAEL PALIN AS KEN PILE IN A FISH CALLED WANDA (1988)
A London gangster's stuttering animal-loving assistant, Ken accidentally kills three Yorkshire Terriers instead of the old woman who witnessed his boss' diamond heist. He's then tortured, forced to watch a double-crossing partner eat his pet fish, so he'll give up the location of the hidden stones. We could hit him with a "cat got your tongue?" joke but we won't—that would just be excessive.
