Actor Robert Pattinson doesn't get demanding on movie sets because he has witnessed crew members giving it back to diva demands.
The "Twilight" star claims crew bosses have all the power on movie sets, not actors and directors - and he has learned to keep his mouth shut, even if he's unhappy, reports contactmusic.com.
"This actress was doing a scene in the bath and she kept complaining about the temperature; how it was too hot or too cold. So everyone p**sed in it and put a bunch of bubble bath in afterwards, so you couldn't smell it! This stuff happens. That's why I avoid asking for anything. I don't want to get anyone's p**s on me," said the 28-year-old.
