His name is Stephen Tobolowsky. If you're a Glee fan, you'll probably recognise him as Sandy, the teacher who was fired for inappropriate behaviour at the beginning. If you managed to get into season 2 of Heroes (I didn't, but I watched it anyway) he was Elle's evil father. In movies, you will have seen him in: The Time Traveller's Wife, Wild Hogs, Failure to Launch, Miss Congeniality 2, Win a Date with Tad Hamilton, Freaky Friday, Memento, The Insider, Groundhog Day, Basic Instinct, Single White Female - and that's just the tip of the iceberg. This guy has been making a living out of being a That Guy since the early eighties! He's also guest-starred in tons of tv series', including Will & Grace, The Practice, The Closer, The New Adventures of Old Christine, Deadwood, Desperate Housewives, CSI Miami, Curb Your Enthusiasm and The West Wing.
Ste-phen To-bow-low-sky. Say it with me now. :-)
