W. will make more money because it will interest both liberals and conservatives because it's about a sitting president. Oliver Stone says it has surprises for both Bush-lovers and Bush-haters.
An American Carol is one-sided attack on the left, which should limit its audience. The protagonist is based on Michael Moore, as a liberal filmmaker "who hates America" obviously just like the real Michael Moore. It also has jokes like "what if 9/11 was done by nuns?" Obviously brilliant.
I'll see W. in theaters, and I'll see An American Carol some day in the future, but I'm not too excited. I haven't seen a good Zucker film in ages. More than both though, I'm pumped for Religulous. I gotta go see that soon.
EDIT: Besides, worldwide more non-Americans will be interested in a George Bush movie than an anti-far-left movie.
