With the fast-approaching release of the 30th anniversary edition of Back to the Future Trilogy, the studio has released a teaser for the short film that features the return of Christopher Lloyd as Doc Brown.

‘BACK TO THE FUTURE’ SHORT BRINGS BACK DOC BROWN

Next month will be the 30th anniversary of Back to the Future, which came out in theaters in 1985. October also marks the month that Marty McFly and Doc Brown arrived in 2015.

The film is celebrating this event by giving fans a sneak peak at the short film Doc Brown Saves the World! which brings back Lloyd as the time traveling doctor. It was announced on Universal Picture Home Entertainment’s YouTube page with a description, “Great Scott, Doc Brown’s back! Here’s a sneak peek from the new short coming exclusively to the Back to the Future 30th Anniversary Blu-ray and DVD Trilogies. #‎BTTF2015”

The short film will be included with the Blu-ray box set of the entire trilogy coming out on Oct. 21, the exact date that our heroes arrive at this time. There will also be new interviews with the cast included in the box set with some behind the scenes footage and some more memorabilia.

Fans can also check out the four-day celebration event in L.A. called ‘We’re Going Back’ taking place from Oct. 21 to 25. The event will feature a tour of where the film was shot, costume exhibits, auctions, a panel with the cast, movie screenings and more.
