George Clooney says he pulled out of Tom Ford's film because of scheduling conflicts, not because they've fallen out.
The fashion designer is dipping his toes back into the world of directing after his highly successful 2009 film A Single Man.
New feature Nocturnal Animals was set to be produced by George, but Hollywood sources say this is no longer the case.
"Ford is in Cannes because George Clooney was to produce the movie through his Smokehouse Pictures, with Grant Heslov. But they had a huge falling out over creative issues a few weeks ago, and Clooney is no longer involved," a source told Page Six.
George rebuffed claims that the men didn't get on though, insisting it just came down to a clash in timings.
"No falling out at all. It was just scheduling. Grant and I love the project and think Tom is fantastic. We just couldn’t do it when he needed to go," George explained.
The 54-year-old actor has been busy promoting his latest movie Tomorrowland. He and wife Amal attended the LA premiere of the flick last week, taking Amal's niece Mia along with them.
He also popped by the Late Show yesterday, where he handcuffed himself to host David Letterman in a bid to stop him leaving the show next week.
"You're not going anywhere, David Letterman," he announced.
"George, is this something left over from the bachelor days?" David quizzed.
"You're not going anywhere," George said again, to which David pointed out that neither is the actor.
"It could make for an awkward evening," George smiled.
"Or maybe not," David joked.
