The sinister grin of Jason Isaacs undoubtedly haunts the nightmares of children and adults alike, thanks to his role as Lucius Malfoy in the "Harry Potter" series. To remain in character, the actor has even gone so far as to avoid answering his fan letters.

"I'm carefully cultivating an entire generation of people who despise me, because when you're in 'Harry Potter' films you get a lot of fan mail ... I haven't answered any of it, so they will hate me even more than they did to start with. They probably spent their pocket money sending me a stamped, addressed envelope."

The British actor recently insisted that while he's enjoyed developing the character, the real payoff will come in the next few films.

"Number four is finished. I'm not signed up for number five; I haven't got a script for [it] yet, but I understand I have some things to do in the book and, if they ask me, then I would be hoping to be in it. Because that is good fun, it's ridiculously good fun to dress up as a wizard ...

I hope that [JK Rowling] writes it until Harry Potter is 65 years old and on a walking frame."
