Stephen Tobolowsky's Long, Long Resume Is Growing

You know those actors who you have seen on dozens of popular shows spanning decades, but you don’t know their names? You probably watch them appear on screen on and think, “Oh it’s that guy from [insert popular show here] — I love that guy!" or "He was in that thing with that other guy.” There’s a term for this kind of actor, a character actor. And while you may not recognize Stephen Tobolowsky’s name at first, you would certainly know his face when he appears on Silicon Valley as Jack Barker, because he is one of the most prolific character actors in the business. Seeing him on the HBO series will only make you want to know what else Stephen Tobolowsky has been in.

According to Deadline, the veteran actor is heading to Silicon Valley’s third season in a recurring role as a "formidable" CEO who will become a new obstacle in the gang’s Pied Piper power struggle. And while those of us who are already familiar with Tobolowsky’s work may immediately recognize him when Season 3 premieres on April 24, there is no way even his biggest fan could know all of his work. With 243 IMDB credits to his name, I wonder if Tobolowsky can even remember all of his work. And, his first credit dates back to 1976 — that’s 40 years in the business, people!

The 64-year-old began appearing on hit shows and movies in the ‘80s, and these guest appearances grew to memorable recurring characters, spots as a series regular, and even roles within the main cast. Though the better question may be, what haven't you seen Tobolowsky in, here are his most memorable TV appearances.*
