As noted by Entertainment Weekly, during an interview with "The Adam Corolla Show," T. J. Miller claimed that he had no active intention to return for the third installment of "Deadpool" because Ryan Reynolds allegedly used his character persona to harass him on set. "As the character, he was, like, horrifically mean to me. But to me," he said. "As if I'm Weasel. He was like, 'You know what's great about you, Weasel? You're not the star, but you do just enough exposition that it's funny, and then we can leave and get back to the real movie.'"
Miller went on imply that Reynolds' alleged actions stemmed from jealousy of both Miller's comedic skill and filmography, and suggested no one who was confident in their own work would say the things that Reynolds' allegedly said. "Would I work with him again?" asked Miller. "No. I would not work with him again. I sorta wish him well because he's so good at 'Deadpool,' and I think it's weird that he hates me."
Throughout these lengthy comments, Miller emphasized that he believed Reynolds to be a fine comedian who should continue to make movies. He also stipulated that he once had similar feelings toward Michael Bay, before in fact working with the director again — though he couldn't resist also implying that Bay, like Miller, had negative feelings about Reynolds. That said, there's some pretty huge reasons why, for many, Miller's thoughts on this matter should be looked at skeptically — namely, Miller's own history.
