Justin Timberlake has been helping fellow stars enjoy the Cannes Film Festival experience.

The actor-and-musician has been at the annual event - which runs from 15 to 26 May - with his 'Inside Llewyn Davis' cast-mates and he's been helping everyone make the most of the opportunity.

At the screening of the drama on Sunday (19.05.13) the actors were assembled on the steps of the theatre before being rushed into their seats and Justin's co-star John Goodman realised he didn't have time to get through the crowd to take a photograph of their big moment.

The 32-year-old star told USA Today: ''As they were yanking us in I said, 'Give me your phone' and I jetted out there.

''I took a picture of it and brought it back in and gave it to him. Everything around here is late except for the screening of the movie.''

The pair appear in the film alongside Oscar Isaac who revealed Justin also helped give him a greater appreciation of their Cannes experience.

He said: ''When we were all standing up on the steps, I was staring into the abyss of cameras and light.

''And Justin was like, 'Look out to the right.' And there was this sea of people all looking to see this (movie) happen. I hadn't even seen that. I was like, 'Oh, man.' It was huge.''
