The top mistakes in Saw IV http://www.moviemistakes.com/film6745 en Sat, 20 Mar 2010 05:55:36 +0000 135280 Several times in the movie you can see a stunt double for Donnie Wahlberg, like when he tries to hang himself. Art runs over and there is a wide shot focusing on both of them. No slo-mo required, but you can see it's a stunt double. 135390 The blood stain on Riggs' white shirt around the neck has blood under the collar, then at the end it is over the collar and has increased in amount. 135407 When Agent Hoffman writes the letter to Amanda, he puts the envelope so her name is pointing down, yet when Amanda opens the drawer her name is at the top. The director had to do this or it would have revealed Hoffman was the new apprentice all along. 135346 When Agent Strahm has finally realised where the final game is being played, he holds up the piece of paper of Jigsaw and Art outside the Gideon building. There is a hand at the top of the picture, which is a newspaper clipping, but he is holding a picture, not a newspaper. This is a reused shot of when he shows Agent Perez the picture earlier in the movie. 147100 When Rigg shoots Art, just before that you can see Art shouting. Look at his chest. The bullet wound is already there (no slow-mo needed).
