Desperate Measures (1998)

Factual error: Peter McCabe escapes the operating room partly by turning his oxygen supply into a flamethrower. 100% oxygen makes everything extremely flammable, but it cannot be lit like a flamethrower.

Revealing mistake: In the scene on the freeway when the semi is sliding sideweays, if you look at the back wheels of the trailer, you can see the wheels making it track straight.

Visible crew/equipment: When McCabe goes into the private cell to break his thumb to prepare for his escape, you can see the top of someone else's head in the bottom right hand corner of the screen. Clearly he is meant to be in the room alone, so it must be crew.
