Bradley Cooper only wants to direct films that he's written himself, and has admitted he has no interest in taking over from James Gunn at the helm of 'Guardians of the Galaxy Vol. 3'.

The 'A Star Is Born' filmmaker - who has also produced and taken the lead role in the musical drama - has dismissed the idea of replacing James Gunn on 'Guardians of the Galaxy Vol. 3' after he was fired by Disney over controversial past tweets.

Presented with the idea of whether he'd be interesting in stepping up if the studio approached him, he told Joe: "In directing it?

"I could never direct anything that I didn't write. No, I could never direct anything that I didn't write."

While Cooper - who plays Rocket Raccoon in the franchise - is yet to fully open up on his feelings around Gunn's exit after two films in the Marvel movie series, he did sign a statement last month with his fellow castmates defending the director.

The statement read: "We fully support James Gunn. We were all shocked by his abrupt firing last week and have intentionally waited these ten days to respond in order to think, pray, listen, and discuss.

"In that time, we've been encouraged by the outpouring of support from fans and members of the media who wish to see James reinstated as director of Volume 3 as well as discouraged by those so easily duped into believing the many outlandish conspiracy theories surrounding him."

Meanwhile, James' brother Sean - who Kraglin in the films and does motion capture work for Rocket - recently revealed Disney is still planning to use his sibling's script for the movie.

He told Tulsa World: "I don't really know yet what's going on with 'Guardians 3'. I know that Disney still wants to make the movie. I know that they have every intention of using the script that my brother wrote.

"Obviously, that was a very unfortunate situation for everybody, most of all him, but I am also somebody who had been preparing to spend half a year making that movie and now that's up in the air."
