Year they first appeared: 1990
Actor: Robert De Niro
Bottom line: Because he’s half Irish, Jimmy will never become a “made” man in the mob, but his ruthlessness is equal to those of any true mob boss.
While he’s generally more cool and calculated than close cohort Tommy DeVito, Jimmy is equally violent and dangerous, and when his neck is on the line, he won’t hesitate to kill anyone who he deems a threat to his livelihood, including people he once considered friends.
Jimmy Conway is based on a real-life mobster, Jimmy Burke, who was said to be far less sophisticated and far more violent than his onscreen counterpart. De Niro makes him seem likable and he offers levity to a dark story with memorable lines, including “Never rat on your friends and always keep your mouth shut.”
