No, not a big deal but I did it once. Stayed up all night and made $40. Lost my best ring in the outdoor toilet, too! It was called "The Cowboy Way" with Keifer Sutherland and one other guy, Woody Harrellson. It was fun.
Peter, if you love doing this, keep doing it. Be an extra. It can lead to more jobs eventually. What about the Actor's Union or is that it???? Imdb? I thought Imdb was just for lists & info on films. There are lots of peoplle where I live who do it, they are extras in films, mainly they get into character acting and boy, oh boy, are they characters! I am interested in this. PM me if you'd like. Best Regards.
