Why don't they just buy a theater and run continuous loops of "Crusader Rabbit" and "Gumby" shows? That should be satisfactory to everyone. Then whoever wanted to cast a Christian vote for the movie business could go to that theater and sit there for two hours.
My point is that Christians are already choosing movies. I'm pretty certain that the crowds I see at the megaplex on Saturday aren't all atheists. They don't look like Muslims, either. Looks to me like the same folks who are going to church on Sunday...well...some Sundays, anyhow.
That's why this plan will fail. If they choose good movies to support, then nobody will notice, since they'll be popular anyhow. If they choose bad movies with acceptable content, nobody will notice either. Or, if they do, they'll think, "Heck, I'm not going to a crummy movie like that," and ignore the group.
If America is overwhelmingly Christian, as I keep hearing, then it is Christians attending the movies. It's already there.
