His episode (the finale of season 1) of Extras is absolutely hilarious. I know he’s not primarily known for comedy, but he’s funny as hell.
he's done a few comedy stints here and there. He played King Richard The LionHeart in Mel Brooks'es Robin Hood Men in Tights plus he was funny in quite a few STNG episodes and movies. He will be missed. That voice and clear diction.
He voiced Stan's boss at the CIA in American Dad. That character wouldn't be as near as funny without Patrick Stewart's competent and authoritative tone of voice.
Sir Patrick Stewart was hilarious when he wanted to be!
Then there was that circumcision disagreement.
