How did Ben Stein's Movie, Expelled, Do Over the Weekend?

I don't have numbers for the entire weekend, but Ben Stein's film, Expelled: No Intelligence Allowed, opened quite well. Another documentary film titled, Where in the World is Osama Bin Laden, also opened this weekend. (It was made by the same guy who made Super Size Me a few years ago.) Here are some early facts from this weekend:

One notable success has been the intelligent design documentary Expelled: No Intelligence Allowed, featuring Ben Stein. Released on a little over 1,000 screens... the film picked up another $1.03 million on Saturday, and it will finish the weekend with just under $3 million. Not bad for a movie shot on a shoestring, released by a virtually unknown distributor and promoted very lightly.

Expelled earned a per theater average of $2800 on around 1000 screens, while Where in the World is Osama Bin Laden earned less than half of that, just coming in at $1373 per theater on about 100 screens.
