Holmes, 36, played the character of Joey Potter on the teen drama and she still carries a part of it wherever she goes, reported Us magazine.
"I don't know if I have moved past it, but I don't really care. I had a ball doing it, and it's really nice to be a part of something that did affect people," she said.
Holmes said the show created a lot of opportunities for all the actors, who were a part of it. "You can't really ask for much more than that," she added.
