Let's face it: the odds of another Back to the Future movie happening are slim, at least during the lifetimes of filmmakers Robert Zemeckis and Bob Gale. But just in case they have a change of heart and decide that a Back to the Future 4 is a good idea after all, there's at least one member of the original cast who will gladly show up for more. Christopher Lloyd, who embodied the time traveling scientist Dr. Emmett "Doc" Brown in the original trilogy, appeared at Niagara Falls Comic Con last month and spoke about his idea for a fourth film in the franchise.
ComicBook.com reports that at the convention, Lloyd said he would be "happy" to reprise his role again in a new movie, but that the theoretical fourth film would need to have a universal message:
"I think somehow it needs to kind of convey a message about something that's important to everyone, universally, like climate change. Some way of incorporating whatever fever is going on at the moment into the film and keep the feeling of one, two and three. That's a tricky, tricky deal. Because you don't want to do another one and disappoint. So I don't know. I'd be happy to, for myself. But we'll see."
This isn't the first time he's mentioned climate change as a possible topic for the sequel. In a 2015 interview with USA Today, Lloyd said, "There's always the danger of sequels not living up to the original, so it'd have to be something momentous and current: dealing with ISIS or climate change or something radical and have a real urgency to it," so this has been on his mind for several years.
