Classic 1980s film Back to the Future has been transformed into a musical by original director Robert Zemeckis.

A stage version of the hit 1985 movie - which starred Michael J Fox as time-travelling teen Marty McFly - will debut in the West End in 2015.

Bob Gale, who co-wrote the three films in the series with Zemeckis, said: "The Back to the Future Musical is a project that Bob Zemeckis and I have been exploring for almost 10 years. We're thrilled to be at last in partnership with a creative and producing team that will create a show that is true to the spirit of the film without being a slavish remake."

Den of Geek further quotes Gale as saying: "We intend to use music from the movie along with brand new songs to make a version of Back to the Future that is fresh, entertaining and takes advantage of all the amazing things that can now be done on stage. We can't think of a better way to celebrate the 30th anniversary of the film."

Alan Silvestri will co-write the music and lyrics with songwriter Glen Ballard.
