Matthew McConaughey has revealed that he won't be starring in The Butler.
The Lincoln Lawyer star had been set to appear in Lee Daniels historical drama as former US President John F Kennedy, where he would have had to swap his Texan drawl for a Boston accent.
"The Butler, it's not going to happen for me. It was going to take some good hard work on my part for sure - and it was more than an accent," he told the Los Angeles Times.
"I've done accents before. And you can see, you can tell when it's just coming out from the neck up. When you see it done well, they walk different, they sit different - it's coming out of their feet. There was a lot of work that I was looking forward to putting in on that. But for certain true reasons, it's not going to happen."
Matthew - who next stars in Lee's The Paperboy and Steven Soderbergh's Magic Mike - said his decision not to do The Butler has nothing to do with the mixed reception The Paperboy received at Cannes.
"No, not at all. I had a wonderful time working with Lee. Lee's become a good friend of mine," he added.
The 42-year-old has been working on Dallas Buyer's Club, which he will star in and co-write with Canadian director Jean-Marc Vallee.
"It was very tough to get the money for that one, being the subject material and it's a period piece," he said.
