We wanted to do a sequel with Jim and Jeff. They said that the word was that Jim didn't want to do any sequels. We approached him and he said he would do it, but not until next year. New Line said it was too long to wait. ↗
They're just not into doing sequels after Toy Story so I don't think that's a possibility. But if they did, well sure, you'd have to do it. And I'd want to do it. ↗
