Actor Christopher Lloyd is reprising his Back to the Future character Doc Brown for a new short film to celebrate the 1985 original's 30th anniversary.
The 76 year old returns as the eccentric inventor, who befriends Michael J Fox's character Marty McFly, for the new short titled Doc Brown Saves the World.
In a teaser trailer, Brown can be seen exiting the famous DeLorean car on October 21, 2015, which is known as Back to the Future Day.
It's the date Doc and Marty travel to in the 1989 sequel.Brown then looks at the camera and fiddles with a handheld device to control an "auto visual tracking" system.
It has not been revealed if Fox will make an appearance in the short, which will be released with the reissue of the trilogy's DVD box set.
