AceShowbiz - Mel Gibson was so intense during the filming of "Lethal Weapon", he left crewmembers in tears with his portrayal of unhinged cop Martin Riggs. The actor surprised his co-stars and director Richard Donner with his emotional performance as the suicidal sergeant, and several of the crew wept during a scene where Riggs contemplated shooting himself following the death of his wife.

Donner tells Total Film magazine, "The camera was shaking because I'm crying, the operator's crying. And I start to get worried about Mel. (He) hit (himself) with (the gun)! And this was after the take was over."

"Lethal Weapon" starred Mel Gibson and Danny Glover as a mismatched pair of LAPD detectives who are hell bent on protecting and serving despite their differences. The buddy cop action film was released in 1987.
