Lethal Weapon 3 (1992)

Continuity: 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.

Continuity: In the scene where the bad guys have taken the Captain hostage and are in the garage about to steal the guns, there's a closeup between the Captain & one of the bad guys talking. As the Captain turns, you can see an extra at the back wall dressed as a cop. He leans forward a little like he's supposed to jump in, then backs off. He's not there before or after that.

Continuity: The scene in the water after our two heroes have been fighting in the boat and Sheriff Dep. boat comes upon them: Notice Riggs's forehead hair - up, down, up, down... and both their hands keeps changing grip on the boat.

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.

Murtagh's boat is called "Code 7". This is the L.A.P.D. code for a lunch break.

When Delores calls herself the "Road Warrior", it's a fairly naked reference to Mel's prior role in the three Mad Max films.
