Arnold Schwarzenegger's first film since
Batman & Robin (1997). The reason for the gap was because of his heart surgery after playing Mr Freeze; the studios were anxious about whether or not they could insure him, and despite attempts to convince them he was in perfect health, he couldn't get any work until
End of Days (1999). Even then, he was amazed when insurance people and executives from Universal came to the set just to watch him, to see if he was still up to the action scenes. They asked Schwarzenegger if he enjoyed this kind of punishment, but he said he was used to it. After the first week of shooting, the insurance guys backed off and not long after, the film offers started rolling in again.
