Screenwriter/Producer Ben Trebilcook contacted us on Twitter to give the real information about Rob and the movie. He's not in it.
According to him
"Robert Pattinson is NOT in my movie"
"The web went crazy with Robert Pattinson news. Unsure of the source. If he wanted in, then OK, but it's NOT true."
"For a list of people who are involved see http://www.imdb.com/title/tt1086065/ Dannii Minogue's character is a good one but not a major role"
"Sorry to say I've never thought or knew about RP before the news of him &my film hit last night! I'd have 2 see Twilight 1st"
"Me and director Peter Pedrero going goggle-eyed at the Robert Pattinson rumours. That's a real stuntman face http://twitpic.com/g2sua"
