"I personally have finished my bit on 'Potter,'" he said. "I'm looking for any excuse to go back, pretend I left things in my trailer, that kind of thing."

"Mostly saying goodbye to the wig was a very emotional experience," he said, deadpan. "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."

Turning serious again, Isaacs described how he's feeling about seeing those final films hit theaters. "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."
