Quite often on a movie like Total Recall you have this training period of two or three months where, like on the first 'Underworld' I was doing gymnastics and trampolining and all this stuff which I don't do in the movie necessarily, but mentally it helps. You come home and you go: 'Well, I've done all that. I must be an action star now!' So it helps you focus a little bit and gets you fit.
One of the reasons I don't like to use the word "tricks" , I do think of them as theatrical pieces, and as pretentious as that might sound, there's a real reason for it. It's not the idea of tricking you; it's the idea of taking you along on this particular journey the way you would in any other theatrical situation. But, hopefully, you're going to be fooled at the end.
