Tim Miller finally talks about his exit from Deadpool and why he quit directing Deadpool 2. Miller became well know following his job on the first Deadpool movie, which earned $363 million domestically and $420 million in the international market and grossed $783 million globally. Miller said one of the reasons he left is to enable the film tell different stories:
“I felt like there was more stories (for Deadpool) to tell there, but I’m happy that somebody else is telling them. There was a sense of relief in that I get to do something new versus Deadpool 2. I think it would’ve been a great movie, but it was also going to be a continuation of what we had done. This really gave me a chance to do something new.”
He added:
“I mean, I wanted to make Deadpool 2. I was going to do that, until I wasn’t. So, there was that, which took up about seven months of my time. But even then, David [Ellison, who has the rights to the Terminator franchise] and I were talking, like after Deadpool 2, it was going to be this [Terminator].”
