John Travolta and Olivia Newton-John want to make Christmas movie

John Travolta and Olivia Newton-John are already making plans for next Christmas - they want to shoot a festive movie on the heels of their 2012 holiday-themed album.

The Grease co-stars reteamed last year to work on This Christmas, a collection of covers and new tracks and Travolta has now revealed they want to add a few new songs to their body of work each year - and the pair has their sights set on reuniting on the big screen for a festive family project.

He tells E! Online, "We're going to try to add a couple of songs every year to that CD. And then maybe do a music video each year so, at the end of it all, we'll have a whole (collection).

"(We want to act in something) Maybe connected to the Christmas idea... maybe a Christmas movie or maybe a Christmas special or something."
