Plot hole: When Sakamoto prepares to deliver his final serve in the tennis match, he declares, "Triple set point." Later we learn that he lost in three straight sets, so the statement should have been, "Triple match point."

Directed by: Arthur Hiller
Starring: James Belushi, Jim Belushi, Charles Grodin, Loryn Locklin, Anne De Salvo
Factual error: When Jimmy hot-wires the Lotus for the last time, he touches a red wire to a black one, the starter engages and the engine starts. Then he twists the two wires together. This would result in the starter running constantly, overheating it, and burning it out. A competent car thief would know never to do that.
Spencer Barnes: I've worked hard to work this hard.
