Based on nothing more than cynicism, I suspect "Saw IV," another bloodbath no doubt (they didn't screen it for critics) will win the box office, simply because these movies attract hordes of young male moviegoers who never heard of, say, Steve McQueen, James Cagney, Groucho Marx, or Barbara Stanwyck. They're welcome to it. I also think "Dan in Real Life" will do well, thanks to the popularity of "The Office." Never mind that "Evan Almighty" was an expensive flop, this one's well acted and likable.
