JLS have told Newsbeat extra dates will be added to the screening of their new movie.

Tickets for Eyes Wide Open were exclusively for one date on 3 June, but sold out weeks before the release.

Speaking at the premiere, Martin Humes said: "Initially we wanted the one date to be an event like a concert, but it sold out at the 300 cinemas across the country with incredible success.

"So we had to add more dates for our fans."

The band say fans will now be able to see the new 3D movie, filmed on their recent sold-out UK arena tour, at cinemas across the country on 4 and 5 June.

The film promises to show "'never seen before" interviews and backstage footage of the group.

"Even the most hardened JLS fans will see bits they haven't seen before. We are not afraid to expose ourselves," said Marvin.

JLS say after the film they are hoping to get back in the studio to finish off the last few tracks on their upcoming album which will hopefully be released by the end of the year.

The foursome's second album, Outta This World, has sold more than half a million copies since it was released in autumn 2010.

"It's amazing to be at our own film premiere - a dream come true to see ourselves on the big screen. We saw it last week with our families and felt very emotional," said Marvin.

When asked about Cheryl Cole's reported departure from US X Factor JB from the band said:

"You know one thing we'll say is when one door closes, another door opens, so obvioulsy wishing her [Cheryl Cole] all the best.

"We're supporting her, we've always been supportive of her. I'm sure she'll bounce back and be great."
