Jason Isaacs, Lucius Malfoy, from the Harry Potter movies is done filming Deathly Hallows"and according to Jason he doesn't get to keep his wig.
While promoting his next film, Green Zone, Mr. Isaacs mentioned that:
I personally have finished my bit on Potter. I'm looking for any excuse to go back, pretend I left things in my trailer, that kind of thing.
It's been nearly 10 years for me. It was very difficult saying goodbye to the entire thing.
Mostly saying goodbye to the wig was a very emotional experience. I don't get to keep the wig. I don't know, it might be on a traveling exhibit. I think it's got a very good agent who's got some more work lined up.
I'm [both] dreading and looking forward to when it says 'The End' because it's the end of a decade of an amazing experience for all of us.
