Gwyneth Paltrow will star opposite Timothee Chalamet in 'Marty Supreme' - her first movie role in five years.

The 51-year-old actress will appear alongside the 'Dune' star, 28, in director Josh Safdie's upcoming film, which is rumoured to be loosely inspired by the story of a professional ping-pong player.

The picture – which is being written by Safdie and Ronald Bronstein – is being produced by A24 and will mark Paltrow's first appearance on the silver screen since 2019's 'Avengers Endgame', where she played Tony Stark's (Robert Downey Jr.) partner Pepper Potts.

Even though she enjoyed her time playing the character – who had appeared in the Marvel Cinematic Universe (MCU) for 11 years after her introduction in 2008's 'Iron Man' - Paltrow had previously admitted she felt like she was done with the superhero franchise.

She told Harper's Bazaar magazine: "I mean, I'm a bit old to be in a suit ... I feel very lucky that I did it, because I actually got talked in to it.

"I was friends with ['Iron Man' director] Jon Favreau. It was such a wonderful experience making the first 'Iron Man' and then to watch how important it has become to the fans."

Despite her long and successful career, the 'Shakespeare in Love' Oscar-winner – who is now focused on her lifestyle brand Goop - insisted her days as a Hollywood leading lady were over.

She said: "I will literally never get a taste for acting again.

"When I was acting I really burned myself out ... I really got to the point where even the little things, like sitting in the van going to set, getting your make-up touch-ups, and everything - I really don't know that I can bear it."

The actress explained she came to this revelation on the set of 2005's 'Proof' when she was pregnant with her 20-year-old daughter Apple, who she has with her ex-husband Chris Martin.

She recalled: "The last movie I starred in, I was pregnant with my daughter. It was a movie called 'Proof', an adaptation of a play I did in London, and I was like, 'I've had it. I can't do this anymore.'

"I had morning sickness and I was dying, and I had these five-page monologues. So when I had her, I knew I was going to take a big chunk of time off. And I've never starred in anything again."
