Deliberate mistake: Early in the movie someone fires an RPG, and, when he does, they show him comically being flung back through the air by some kind of supposed recoil effect. RPGs are rockets shooting out of tubes with the blast going backwards, so the holder of the tube themselves experiences no recoil.
Half Past Dead (2002)
1 deliberate mistake
Directed by: Don Michael Paul
Starring: Steven Seagal, Morris Chestnut, Ja Rule, Nia Peeples, Matt Battaglia
Factual error: A two minute free fall from a helicopter? Not unless the helicopter was flying at 230,000 feet, which is more than 5 times the record altitude achieved by one.
Lester: The rumor is you went half past dead and came back.
Sasha: Yeah.
Lester: Took a ride on the flat line for 22 minutes... and lived to tell. Thought we could play some cards and talk about that.
