He's entirely right. Sure, it was a surprise to see him in some of the reviews I saw for the Chipmunks movie, but this is how non-mainstream actors do their thing. The term "sell out" is a sell-out. It doesn't mean anything anymore. It used to mean someone who would ruthlessly do anything for money without regard for what it really meant, regardless of how much they already had. Cross, like many artists of varying sorts, does what he needs to do to get by, just like plenty of us regular people. He does stuff like this so he can continue doing the stuff his fans actually like. (Think about that the next time you make fun of all those "one-hit wonders," etc. - more often than not, that one hit is what enabled them to continue being musical artists rather than simply entertainers, and that's all they really want.)
