Stewart is hilarious in interviews. I saw him on The Caroline Rhea Show. She had him reading Hip-hop lyrics. He was a scream.
I can take him in small, very small doses. I had the misfortune of hearing Stewart speak at a Trek convention in Dallas several years ago. He yammered for two solid hours about the Royal Shakespeare Company and summer stock theater in Bum**** Egypt or somewhere; fascinating stuff if you're in the trade, but a snoozer of a topic for a general audience. I actually walked out after about an hour and haunted the vendor's tables for the rest of the speech. While I stand in awe of his acting abilities and enjoy his work in general, he really was a boring, tedious little man in person. Maybe I was just having a bad day.
Jonathan Frakes was at the same convention; my brother browbeat me into taking a trombone and a brand-new mouthpiece with us to the con and trying to get him to play it. But, true to form, we chickened out at the last minute and didn't do it. Wasn't drunk enough I guess. We did get to have a drink with him after the show though; we caught him sitting at the hotel bar pounding down a club soda, just like folks. My brother got starstruck after a minute or so and just shut up, but Frakes told me about his Lyle Lovett obsession and the fact that Lovett is about all he listens to in his car. I got the impression that there is a "there" there when it comes to Frakes, and I enjoyed talking to him.
