David Cross has never hid the fact that he, like probably everyone else involved, only does Alvin and the Chipmunks films for the crazy money 20th Century Fox pays people to pretend to interact with CGI animals. In a 2008 open letter, Cross went on the defensive to point-by-point rationalize his decision, basically explaining that comedy nerd cred cannot buy a new house. That point remains irrefutable today, but still the comedian recently felt the need to again defend his being in three of these fucking things.
Speaking during press rounds for IFC's The Increasingly Poor Decisions of Todd Margaret, Cross explained he "was contractually obligated to do three, which is kinda standard." And now that he's free from that contact, he went on to explain how shitty it was to swallow his pride like a CGI chipmunk chokes down feces, appearing in an additional squeakquel. The beloved comic who has a credit in both Scary Movie 2 and Dr. Dolittle 2 told reporters:
This last [squeakquel] was literally, without question, the most unpleasant experience I've ever had in my professional life. It's safe to say I won't be working with some of those people ever again. Not the actors. And the director [Mike Mitchell] was great. We got along. There were a couple of people, though...it was just a really awful, unpleasant experience."
Fellow live-action franchise star Jason Lee, meanwhile, has said nothing so harsh about the production, as he still remembers Underdog.
