Sometimes, if you're shooting a complicated scene, you have to stay in a position and wait for the technician to do his job, and then you have to be where you're supposed to be, right on the spot. You don't rehearse all that much on films. If I think of the amount of time I spend on set compared with the time spent shooting, it's ridiculously short.
To wait, for an actor, is not like someone who's waiting to see the doctor. It's not the kind of wait where you get bored.
You get involved with a character after spending a long time waiting, and this demands a lot of energy and concentration.
