Cassidy's character Zach was Seth and Summer fans' enemy number one in season two after it was revealed he was dating Summer. (And he played water polo!) He was later kidnapped by George Lucas. (Not really, but he took a meeting with Lucas and was never heard from again). Since the teen drama, Cassidy has appeared on Smallville, Privileged, Scandal and currently stars on TBS' Men at Work. He also had a small role in Ben Affleck's Argo.
