That's why Cross has no desire to do a sequel or any other film with the Chipmunks team, saying, "I would never work with any of those people again for the rest of my life."

While the Arrested Development alum appeared on camera for the live action films, the singing chipmunks Alvin, Theodore and Simon were voiced by Justin Long, Jesse McCartney and Matthew Gray Gubler, respectively. 

As Cross put it, "I think I contributed quite a bit to this billion dollar franchise."

E! News has reached out to 20th Century Fox for comment on the allegations but hasn't heard back. 

After first speaking out about his experience a decade ago, Cross clarified that he has no complaints against producers Ross Bagdasarian or Janice Karman—the son and daughter-in-law of Alvin and the Chipmunks creator Dave Bagdasarian.

“Janice and Ross were never anything but warm, giving, and gracious to me,” he wrote on Facebook in 2012, per The Hollywood Reporter. “From the first day I walked on the set for the first movie to wrapping the third. During the shooting of Chipwrecked they went out of their way daily to make sure that (as my negative treatment was well known to everyone involved) I was happy and they understood and appreciated my situation."

Cross—who said he only had issues with an unnamed producer—added at the time that he admired Karman and Bagdasarian's "enthusiasm, energy and spirit," saying, "They're really, really nice and I can’t imagine them ever behaving that way to anybody.”
