Movie extra? what is your experience?

do it! you get paid and get to be in a movie.... they were filming for "zack and miri make a o" (seth rogan) where i live and it was pretty cool, i had to walk past him and bumped into him by accident.. usually they wanna have the extras on set really early but that varies with the movies and you'll probably be working for 8 hrs but who cares your getting paid and its pretty fun....and they feed you :)
