Au Contraire.
That's a PLUS - no big name actor whose persona would overshadow the role
I understand what you're saying. But, in the practical business world of Hollywood, that makes things a LOT more difficult to get a wide release.
Unless the picture has A-list talent, or an A-list director and/or a massive special effects budget, it is very difficult to get very many people to see it.
There are some rare exceptions, but generally those are indie films that have done exceptionally well on the film-festival circuit. That success will sometimes be enough for a major studio to buy the film, even though it's a small-budget, no known talent and brand new director feature film. As far as I can tell, this film wasn't screened at a single film festival. That's not a good sign. I'm not optimistic.
By the way, this is why I think what Mel Gibson was able to accomplish with Passion of the Christ was so incredibly remarkable. He did have a larger budget - at least twice what this film has - but he used every penny wisely, and he created a genius, textbook really, grass-roots marketing strategy. I think these guys would have been smart to screen the whole film at CPAC. The fact that they didn't says one of two things - either they don't know what they're doing, or the film isn't that good, sadly.
