Is his career over?

Irrelevant for 7 years now .. Shame always liked him

Kinda sad to see Jason do the Alvin/Chipmunks movies. I always loved him as an actor. Shame he couldn't get a good TV role or good movie roles.

He's up to 4 now.

First, Jason Lee is now a family man. He admitted to doing Alvin and the Chipmunks for his kids. I'm pretty sure he doesn't want his children to ever see some of his raunchier films.
Second, do you realize the number of struggling actors working while waiting tables that would kill to star in 4 hit films? Alvin and the Chipmunks definitely was not a career killer.

He's top-lining a pilot this year, so I'd say no.

Wrong, he is finished in Hollywood according to everyone that knows things in the biz.

Serious question, is it due to him by his own choice or his behavior or he's not as relevant anymore?
