Back to the Future Part II

At a convention Q&A session, Christopher Lloyd recalled being one of the cast and crew invited to the film's Royal Premiere in London. Since Michael J. Fox couldn't attend, he was one of the first to greet members of the Royal Family, including the late Princess Diana, and was able to sit near her. Lloyd recalls that the loudest the Princess laughed during the film was the scene where Biff has a truckload of manure dumped on him.
