Back to the Future, released in 1985, is touted as one of the most successful films of the 20th Century and made movie stars out of a largely unknown cast. Here’s what to expect when the REELZ premieres Back to the Future: Behind Closed Doors on Sunday, June 28.

“I’ve never done anything that has meant so much to so many people,” says Christopher Lloyd, whose role as Dr. Emmet Brown thrust him into the Hollywood spotlight as soon as the movie opened in July of 1985.

“What I remember most is Lloyd’s inflections,” adds Michael J. Fox who starred in the blockbuster as Marty McFly. “It’s not so much the lines I remember, but just like, you know, Marty! Marty!!” recalls Michael, who became one of Hollywood’s most bankable stars after the movie broke box office records.

The unlikely hit spawned two sequels, an animated series, a theme park ride at Universal Studios, a video game and a musical. The film’s stars still marvel at its lasting appeal and fan base, 35 years after its initial release.

“It’s funny, it’s profound, it’s heartwarming, it’s perfectly made,” says Lea Thompson who costarred as the time-traveling Lorraine Baines.

The documentary, hosted by Natalie Morales, reveals the inside story of how the film finally got off the ground after it was rejected more than forty times before finally being greenlit by Universal.

Get all the details from the cast and crew as Natalie hosts Back to the Future: Behind Closed Doors, Sunday, June 28 at 8 ET / 7 PT on REELZ.
