Jessica Chastain has told how Anne Hathaway has given her a few tips on how to play an astronaut in her next movie.

The two actresses walked a blue, star-spangled carpet in London’s Leicester Square for the premiere of Christopher Nolan’s space epic Interstellar, in which they star with Matthew McConaughey and Sir Michael Caine.

The movie sees Anne and Matthew’s characters go on a mission into space after Earth becomes uninhabitable, while Jessica plays a scientist who stays at home.

Jessica, who wore a pink Yves Saint Laurent gown, said: “I loved my character so much and I wouldn’t have traded her for anything. And to me the heart of the film is about the powerful bonds of love….

She added: “My next film – I’m going to go play an astronaut! So Annie gave me some advice about what to do with the space suit and everything.”

Jessica is about to begin working with Ridley Scott and Matt Damon on The Martian.

Meanwhile, Anne, who wore a chainmail dress by Wes Gordon, was asked what luxury she would take into space.

“I’d take the best sound system I could buy. I would need some music,” she said.

Matthew, who was accompanied by his wife Camila Alves, said all audiences can still relate to the family bonds his character has, despite being a space traveller.

He said: “The whole hook where everyone will be able to understand this film on an emotional level is- everyone’s had to say goodbye. To a father or their kid.

“Sometimes that’s a first day at school, sometimes that’s when dad goes off to work. This is the most extreme circumstances of that. And it’s also about keeping a promise to your child.”

Interstellar is released in London on November 4 and goes on nationwide release on November 7.
