I haven't seen the film, so I have no opinion of it one way or the other. But I have to question the wisdom of opening any film the same weekend as the latest Batman film and the release of Mamma Mia. Batman: The Dark Knight will easily gross more than $100 million and there are predictions that it might go as high as $170 million. Mamma Mia is based on a huge Broadway hit with many successful road companies. There can't be a lot of money left in the pool after those two films suck up their share. The same article predicting the Batman gross is predicting Space Chimps to gross $6-8 million.
While I have no idea when the Space Chimps DVD will be released, it's likely to be for Christmas, where it will be up against Wall-E, Kung Fu Panda and the latest Looney Tunes compilation. A strong theatrical marketing campaign and good box office gross would have helped the Space Chimps DVD release, but it doesn't look like that's in the cards.
My sympathies go out to the crew of this film. A lot of hard work is going to go unnoticed.
