While fans of epic classic science-fiction movie "Back to the Future" are all set to celebrate "Back to the Future Day" on 21 October (the day Marty McFly and Doc arrived in the future in 2015), it seems that Christopher Lloyd, who played the iconic character of Dr. Emmett (Doc) Brown in the trilogy, is more than willing to act in another sequel, if it happens.

In an interview with The Hollywood Reporter, he said that he would love to sign on immediately if the original cast of the movie including Robert Zemeckis, Bob Gale, Michael J. Fox, Lea Thompson and Thomas F. Wilson will get back together.

"I would love to do Doc again, no question," Lloyd said.

He also said that as predicted in "Back to the Future: Part II," he will "like to toss out the first pitch if Chicago Cubs get to the World Series."

The franchise, which broke all the box office records at the time of its release, has been in spotlight recently as the date 21 October, 2015 approaches. The date is the same one when Marty travels to the future from 1985 as was shown in "Back to the Future: Part II."

Earlier this year, Robert Zemeckis, director of the trilogy, had dismissed all the ideas of a fourth sequel in an interview with The Telegraph saying that "another 'Back to the Future' movie will be made over my dead body." However, Lloyd is hopeful that if it happens, he is definitely going to be in it.

"It's tough to come up with an idea that contains the excitement of the original three," the 77-year-old actor said. "So it would be a real challenge for the writers to come up with an original Back to the Future story that has the same passion and intensity and excitement as the other three. But it could be done, you never know."

Recently, Lloyd appeared in a Toyota car commercial with his fellow BTTF actor Michael J. Fox. The commercial is the latest in a line of stunts that include release of hover-boards and Nike's Power Laces, as shown in the trilogy, designed to promote Back to the Future Day on 21 October, 2015.
