Despite initially being rejected by various studios, when the film was eventually released in 1985 it became the most successful film of the year, grossing more than $383 million worldwide and receiving critical acclaim.
The trilogy remains a global phenomenon and has spawned an animated series, theme park ride, various computer games - and an upcoming musical.
Gale and Zemeckis are currently working together again on the material, which it was announced will be released in 2015 - although Gale told Yahoo that this was categorically not true.
Composer Alan Silvestri, who worked on the film trilogy, will write the music. Gale is writing the book and producer Greg Ballard, who co-write hits such as Michael Jackson's "Man in the Mirror", writing the lyrics.
