Chill Factor (1999)

Revealing mistake: In several scenes (e.g. in the deli & in the tunnel, at the end) the ice cubes used to cool Elvis down are obviously not real ice.

Continuity mistake: After the two main characters sled down the mountain in that boat, they all fall into the river. In the next shot, they come up from underwater, and the boat miraculously is right-side-up with no water in it.

Other mistake: In the scene where Cuba and Skeet are "negotiating" with the federal agent at the end of the movie, Cuba interrupts Skeet by saying, "I'll handle it from here sweetdick." Notice that Skeet almost breaks character due to an apparent ad-lib by Cuba.

Arlo: You just hijacked me with an unloaded gun?
Tim Mason: Yeah.
Arlo: When this is all over, remind me to kick your ass.

Arlo: We're heroes, my man. It's time to start acting like it. Quit limping around like that.
Tim Mason: Excuse me, I got a bullet in my leg.
Arlo: Always the negative with you.
