Lethal Weapon 3 (1992)
1 character mistake
Directed by: Richard Donner
Starring: Mel Gibson, Danny Glover, Rene Russo, Joe Pesci
Continuity mistake: In the hockey game, the teams playing are the Los Angeles Kings and the Toronto Maple Leafs. You can notice the real logos when the camera is away from the action. When it gets closer, though (probably because of copyrights), the maple leaf is turned into a spades (from cards) with only "Toronto" written and the Kings' word and crown in the logo become just an "LA" with a slightly different shape.
Riggs: I can't shoot a dog. People? Okay, but not dogs.
Trivia: The building that explodes in the beginning of the film (due to Mel Gibson messing with the bomb) was the old city hall in downtown Orlando, Florida, where the scene was shot. In reality, only half the building collapsed from the explosion.
Question: Touching Lorna's computer Riggs unintentionally started a Three Stooges game which Lorna claimed to be a weapon. Why?
Answer: She didn't want him to see that she was a fan of those comical idiots. She was supposed to be a tough nonsense internal affairs officer. She was in fact his soulmate, exactly like him, wild and crazy.
