Aren't actors wary of "original" movies, to start with? I've always been under the impression that remakes and sequels are their preference. They know the picture has a greater chance of success and they want to be associated with that. STAR WARS is 40 years old, but we know it's a draw. Even with some known quantities, though, they're like the Kiss of Death. How many are really going to feel the need to go see Shakespeare's "Hamlet"? People don't want to feel "shafted" seeing untried movies, as expensive as they are now. At the same time, there are a very few theatres (in Philly, I know we have one, but we're a college town, anyway) that show nothing but original movies from maverick film makers ...
Often Artsy, film-school type fare. Flicks shot on someone's cellphone, with available lighting and the actors star in whatever clothes they happen to have on. Those kinds of features. In fact, I know a Producer/Director named Mike Belinski who hasn't done too badly for himself making movies, Roger Coreman-style. His most successful effort has been the "Amateur Porn Star Killer" series. He invited me to participate as Art Director for a zombie movie he was making a few years back, but my schedule simply wouldn't let up and I ended up losing that opportunity, unfortunately.
