Actually my friend made the props for MI 3. I saw the film with him yesterday. He made the camera, the bombs, the mask making machine and a number of other props. He said it was very tight security and that while making the props they had to vault everything when not being worked on. He said they made about twenty bombs and most of them disappeared by the end of the film. I'm still mad that he got me nothing even though he knows I'm a prop freak.
