Double Team (1997)

Revealing mistake: When Quinn is ambushed at his home one shot shows the female caretaker lob a grenade at him before he kills her. It falls to the pool. However, when it explodes, you can see that the explosion is above ground. A further shot shows the pool exploding after that.

Factual error: When Quinn and Yaz jump out of the little sportplane, they use his little ball-parachute thingy. When it opens they just fall out. No foam, no stuffings. Nothing. Technically, they would have been smashed like bugs into the ground.

Revealing mistake: During the shootout at Quinn's home, the underwater shot of Quinn diving in his pool, you see bullets dive directly down. This can only be possible if someone was directly on top of him but you don't see any bad guy anywhere near the pool or overhead for that matter.

Yaz: What's wrong with my clothes?
Jack Quinn: You look like a carrot with earrings.

Jack Quinn: Who does your hair, Siegfried or Roy?
Yaz: The last guy that made fun of my hair is still trying to pull his head outta his ass.
Jack Quinn: I don't wanna know about your sex life.

Stavros: You know, Jack... I can call you Jack, can't I? I bet there's not a single night where you can close your eyes tight enough without seeing my little boy's face. I'm gonna give you a chance to know your son. If you live today, you'll get to know your son. And if you don't, I'll raise him as my own. You know, men are strong, Jack, but the tiger is stronger. Oh, one more thing, Jack. There's nothing wrong with stepping on a mine. It's stepping off that counts.
