I saw an interview yesterday with some members of the cast of Red Dragon. The interviewer chick asked Anthony Hopkins if he enjoyed playing Hannibal Lecter, he said oh yes, it's a great role to sink your teeth into, blah blah blah, and then she asked if he hoped to do a fourth Hannibal movie and he said 'well yes I would, but we'll just have to see what happens.'
Does no one understand the movies are based on the books? Can't very well do a fourth movie if there is no fourth book.
