'Back To The Future' Cast Reunites To Reminisce About Hoverboards, Kisses And... 1.21 Gigawatts!

It's hard to believe that it's been 25 years since Marty McFly first hopped in a DeLorean and traveled back in time, 25 years since Doc Brown first screamed "1.21 gigawatts!," 25 years since Marty's mom accidentally tried to put the moves on her own son, and 25 years since "Back to the Future" became a pop-culture phenomenon that spawned two sequels and a deluge of still-quoted one-liners. Ah, but it has... and as proof, the cast and filmmakers gathered in New York City last night to celebrate the release of the "Back to the Future" Trilogy 25th Anniversary Blu-ray Collection.

MTV News was on hand for the red-carpet event and was able to "go back in time" with stars Michael J. Fox, Lea Thompson and Christopher Lloyd, as well as director Robert Zemeckis, all of whom reminisced about their favorite lines and scenes from the movie and the questions they most often get from diehard "BTTF" fans.

"The thing that people ask me about more than anything else is the hoverboard," Fox (a.k.a series hero Marty McFly) said of the flying skateboard he rides in "Back to the Future: Part II." "People want to know where they can get a hoverboard. I don't know. I wish I had a hoverboard because I was hanging from cranes and swung through the courtyard, dangling like a puppet and a hoverboard stapled to my feet."

Meanwhile, Thompson, who played Marty's mom Lorraine, still has a soft spot for the line Lorraine uses to describe Marty, who she doesn't know is her son from the future and who she thinks shares a name with a famous brand of underwear: "Calvin Klein! He's an absolute dream." Yeah, there's a whole lot that's both weird and awesome about that.

Zemeckis also shares Thompson's fondness for the slightly inappropriate. Referring to a line uttered by Lorraine after she kisses a mortified Marty, the director laughed, "My favorite is: 'When I'm kissing you, it's like I'm kissing my brother.'"

Lloyd, famous for his portrayal of wild-eyed, wild-haired Doc Emmet Brown, shared that fans still quote lines back to him all the time. And, while he does get "1.21 gigawatts!" screamed at him an awful lot, he said that doesn't compare to the popularity of "Great Scott!" and the forever timeless "Roads? Where we're going we don't need roads."
