Danny Boyle has said that it was disagreement with producers over working with his long-time writing partner John Hodge that led him to walk away from Bond 25.
Boyle signed up to direct the movie in March last year, along with Hodge, whoâ€™d written an original story for the franchise, but by August he had stepped down, citing â€˜creative differencesâ€™.
True Detective director Cary Fukunaga later took over the job, but now Boyle has spoken a little about what happened.

â€œI learned quite a lot about myself working with Bond. I work in partnership with writers and I am not prepared to break it up,â€ he told Empire.
â€œWe were working very, very well, but they didnâ€™t want to go down that route. So we decided to part company, and it would be unfair of me to say what it was because I donâ€™t know what Cary is going to do.
â€œI got a very nice message from him and I gave him my best wishesâ€¦ it is just a great shame.
â€œWhat John Hodge and I were doing, I thought, was really good. It wasnâ€™t finished, but it could have been really good.
â€œYou have to believe in your process and part of that is the partnership I have with a writer. Itâ€™s like saying â€˜Hey, we are going to give you a different editorâ€¦â€™ Those fundamental partnerships are vital.â€
Boyle has worked with Hodge on many films, from his breakthrough Shallow Grave to the sequel to Trainspotting.
A number of rumours emerged around why Boyle and Hodge quit the movie, including Boyleâ€™s choice of a potential villain.
It was also rumoured that the pair wanted to kill Daniel Craigâ€™s Bond off at the end of the movie, and Boyleâ€™s comments donâ€™t necessarily dispute that possibility.
After leaving the production, writers Neal Purvis and Robert Wade returned to the fold, having penned every Bond movie since The World Is Not Enough through to 2015â€™s Spectre.
Writer and director Paul Haggis then worked on a re-write of the script, as did Scott Z. Burns.
Itâ€™s now thought that Bohemian Rhapsody star Rami Malek is circling the role of the movieâ€™s villain, with Lea Seydoux, Naomie Harris, Ben Whishaw and Ralph Fiennes all reprising their roles.
Bond 25 â€“ thought to be using the working title Eclipse â€“ is due out in April, 2020.
