Rambo III (1988)

Continuity mistake: Rambo has a cut on his left cheek bone that is forever getting smaller, bigger, scabby and in some scenes it's gone. Sometimes it's white, sometimes red. This all happens in one day.

Mousa: You do not look like men Griggs sent before. You not look like you are with military.
Rambo: I'm not.
Mousa: What you are? Mercenary?
Rambo: No.
Mousa: You're not with military, not mercenary - what you are? Lost tourist?
Rambo: I'm no tourist.

Trivia: On one scene where Rambo is walking side by side with Col. Troutman you can see the wound in Rambo's side that he cauterized with gunpowder. (this shortly after Troutman was rescued from the Russian prison camp) The wound is about 1" in diameter and goes all the way through him. In other words you can see the background scenery right through the wound. Weird. Also, towards the end of the movie where Rambo is crawling on the ground with a Molotov cocktail in his hand right before he throws it at the tank, he gets shot in the leg. Same visual effect. Again the wound is about 1" in diameter and the background scenery is visible straight through the wound. Both of these instances are in a blink of an eye so you may have to go frame by frame to see them. Sounds like the special effects guys simply couldn't resist having some fun with this.
