They had regular Equity auditions - someone has already said that Marshall has several pros coming in towards the end. It's all completely bogus and furthermore filled with outright lies (the couple who broke up - scripted reality TV - there's a concept). Touting Jim Jacobs as a Broadway veteran (one B'way show does not a veteran make - and they also act as if he had something to do with the film - he and his partner were not allowed on the set, that's how much he had to do with it - and, of course, the two hit songs from the film are by John Farrar), touting Miss Marshall as a Tony Award-winning director (she has never won a directing award, Tony or otherwise), touting David Ian as a B'way veteran (sorry, he produced Saturday Night Fever in London - and even if he'd produced it on B'way, producing THAT show only makes you an idiot, not a veteran).
