With the 30th Anniversary of Back to The Future rapidly approaching, some fans are wondering whether all of this attention could pave the way for a new sequel. Director Robert Zemeckis shot down rumors of a potential remake earlier this summer, since both he and screenwriter Bob Gale control the rights, and he doesn't expect to see a remake until after they're both dead. The director didn't say anything about a sequel, and while nothing appears to be set in stone yet, franchise star Christopher Lloyd revealed to The Hollywood Reporter that he would be open to returning as Doc Brown in Back to the Future 4.

"I would love to do Doc again, no question. It's tough to come up with an idea that contains the excitement of the original three. 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."

Yesterday, Toyota debuted a new Back to the Future-themed ad where Christopher Lloyd and Michael J. Fox are reminiscing about all of the predictions from the year 2015, as seen in Back to the Future Part II, that actually came true. The car manufacturer will release the full video on October 21, the actual date Marty McFly (Michael J. Fox) and Doc Brown (Christopher Lloyd) travelled to in Back to the Future Part II. When asked if he thinks Michael J. Fox would also come back for Back to the Future 4, Christopher Lloyd had this to say.

"I think regardless of the Parkinson's, he'd probably jump on the role and he'd be great. I can't see doing another sequel without him. I would certainly want Bob Zemeckis directing it, Bob Gale writing it and the other principals being involved. (The DeLorean) was such a perfect choice for the film. It looked so speedy and futuristic."

Fans will be able to watch the entire Back to The Future trilogy in theaters on October 21, and a new 30th Anniversary Blu-ray and DVD set will be available on October 20. It's clear that fans certainly haven't forgotten about Back to The Future, 30 years later, but do you think they would embrace another sequel, if Christopher Lloyd and Michael J. Fox came back as Doc and Marty?
