Oh, how time McFlys.

The time-traveling flick “Back to the Future” first revved its engines in theaters July 3, 1985. Great Scott, that was 30 years ago. And original fans like myself are getting grayer than Doc Brown. But that doesn't mean we can't fire up our virtual DeLoreans and celebrate with a road trip.

Roads? Where we're going, we don't need roads.

So what’s the reason for the revelry? October 21, 2015 marks the day in the film when our ski vest-wearing hero, Marty McFly (Michael J. Fox) hopped across the space-time continuum into the future. Many theaters throughout the country are showing the films, and a new "Back to the Future" trilogy Blu-ray box set hits stores today.  

And if you’re up for an impromptu trek, there are several ways to share the power of love for this sci-fi trilogy. 

Washington West International Film Festival

While playing host to this film fest Oct. 21-25, the town of Reston, Va. renames itself Hill Valley in honor of “Back to the Future.” All three “Future” movies screen at the festival. On Sunday, Oct. 25, Christopher Lloyd (Doc Brown) and other members of the cast and crew will appear at a red carpet screening of the original.

“Back to the Future” Celebrity Cruise to End Parkinson's Disease

Who needs a time-skipping DeLorean when you have a cruise ship? Hop aboard Oasis of the Seas, Royal Caribbean's largest ship, for a seven-day cruise out of Ft. Lauderdale, Fla. (Nov. 7-14). Along the way, the Oasis of the Seas stops in Haiti, Jamaica and Cozumel, Mexico. Cast and crew members from the trilogy set sail with you. Marc McClure, who played Marty’s bro, and Don Fullilove, Hill Valley’s Mayor Goldie Wilson, and others interact with guests and sign autographs. Special events include an Enchantment Under the Sea dance featuring a band including actor Harry Waters, Jr., who played Marvin Berry in the original. Proceeds help benefit Team Fox and Parkinson's Disease research. 

We’re Going Back

If you can get to Los Angeles, a heaping helping of “Back to the Future” events begin today and drop throughout the week. We’re Going Back events include a tour of the Universal Studios backlot, a screening of “Back to the Future Part II” and riding a hoverboard with members of the trilogy’s actual stunt team.

The Million McFly March

Grab that ski vest for this one. Participants are asked to don their flyest McFly threads and meet at the Burger King in Burbank, Calif., a location for the first film. It takes place today (Oct. 21) from 9 a.m.-6 p.m. Proceeds help benefit Team Fox and Parkinson's Disease research. 

Atlanta's BTFF Party: Oct. 21, 2015

"Future" fans who can drop everything and head to Atlanta will find a trilogy-themed bash taking place 8 p.m. at the Masquerade nightclub in Poncey-Highland. Partiers will be slurping down themed cocktails with monikers like The Flux Capacitor and 1.21 Gigawatts. A costume contest and a live show by the burlesque infused Art to Life troupe are part of the equation. DJ Rev. Andy spins 1950s dance tracks, while DJP time jumps us to the 1980s and beyond. A limited edition clock tower pin will be sold at the bash. All of the proceeds from the event will benefit Team Fox, an organization put together by Michael J. Fox to fund Parkinson's research.  

Christopher Lloyd Q&A

A few years ago, I had a chance to chat with Christopher Lloyd, aka Doc Brown in the “Back to the Future” trilogy. So I decided to turn back the clock and dig this one up.

Your role as Doc Brown in “Back to the Future” is something that seems to keep coming back, whether it’s video games or other projects.

Christopher Lloyd: It’s amazing, because back when we did the film and it was released we were just hoping it would have a good run. And then the sequels came up, two and three, and it just doesn’t die. [Laughs] It just keeps manifesting itself in one way or another, and it’s a delight. It’s especially gratifying that so many generations [have enjoyed the movies.] Parents come up to me who were children when the film first came out 25, 26 years ago. And they now have kids who have seen it and are as enthralled by the trilogy as they were. So it just keeps running along, and it’s wonderful to see so many people loving a film that meant a lot to them. Many people come up to me who saw the film when they were young, 10 or 12 years old, and they say it changed their lives and gave them a direction. It’s just great to see that and be involved in a project like that.

Why do you think “Back To The Future” has such staying power?

Time travel is a universal fantasy I’m sure we all have. At one point or another we think, “Gee, if I could go back to this or that time in the past, or if I could just jump ahead 50 years or 300 years into the future to see what that would be like.” It’s kind of a universal fantasy and the film kind of answers to that. And then there’s the relationship between Doc Brown and Marty. It’s a classic mentor relationship. There’s this young man who has this older guy who fascinates him because of his spirit of discovery and the excitement of that. Finding out about new things and new ways life can be lived I think is another great universal situation. And it’s a family picture. There are the time travel aspects between Doc and Marty, but Marty has a family. And we see that family evolve. It’s got a lot going for it.

I read that out of the three “Back To The Future” films, the third one is your favorite, because it’s a Western and a love story.

That’s right. Doc meets somebody he falls in love with, something he did not include in his life. His life was [about] inventing things, being a scientist and inventing time travel. So he had no time for romance. And then bingo, out of the blue comes this lady, and he’s just blown over by her, totally smitten. So that’s a lot of fun. ...And it’s a Western. Westerns are always exciting with horseback riding and all that business. So out of all the three that was the most fun for me being Doc.

Back to the Future: The Ride

Both Universal Studios Florida and Universal Studios Hollywood theme parks opened Back to the Future: The Ride, a simulator-based attraction, in the early 1990s. In 2007, both parks replaced it with The Simpsons Ride. Although it didn't stand the test of time, its video footage lives on YouTube.
