According to the actor, the film should carry an important promise to be eligible for existence. Christopher Lloyd told about this in a conversation with ComicBook: "I think the continuation should transfer to all the important message for the world, for example, a climate change. Somehow the film should combine people with a common problem and at the same time maintain the spirit of the first three parts. " The actor also explained that this is a very difficult task, because he would not want another film to be born and disappointed fans.
Lloyd noted that he would happily agreed to reveal in the continuation of the adventures of Marty Macflage and Dock Brown, if Robert Zeekis and Bob Gale approved this venture. But for many years, the position of Zeekis remains the same: a new film is only through his corpse. Many fans of the original trilogy support his opinion and agree that nothing good can happen from the continuation. Lloyda has been 80 years old, Michael Ja Fox has long been suffering from Parkinson's disease, and no one will approve new actors. With all these circumstances, fans converge in one thought: it is better to touch the holy to anyone.
