The comically irritating rich kid on my all-time favorite sitcom "Dobie Gillis" was played by an actor named Steve Franken, who has died, at the age of 80. The original rich jerk on the show was Milton Armitage, played by Warren Beatty, but he left the show early and Chatsworth stepped in to be totally unlikeable and ridiculous.
I wish I could find a good clip of him as Chatsworth on YouTube. But here's Franken playing a drunken waiter in the 1968 movie "The Party" (with Peter Sellers). It's not a silent movie, but Franken's role is silent (and very funny).
