Other than that.. I worked in a card shop as a teen and met several players, including Mr. autograph himself, Bob Feller. I never knew what to say to them, always felt like a fool (don't just stare... say something, anything, ya big dumba--- lol)
Met George Takai when I worked a booth at a convention, he was very cool and friendly, and before the doors opened, he went around to each table and looked at our wares and spoke to us (this was a small con). I don't remember what I said to him, but he was the kind of person who could put you at ease... so I didn't just stare and say nothing like a big dumba---
Stan Lee - he was the youngest 90-something-year-old I ever met, just full of pep, I thought, "this guy's going to live to a hundred and ten!" but sadly, his health took a downward turn shortly after and he was gone only a few years after this.
I also worked at both card shows and comic shows over the years, and I've met many sports (mostly baseball) players, sci-fi and nostalgia actors, comic book writers and artists, and more. Some were very nice, and some were so rude that they made you wish you never met them.
The nicest of the sports starts I met was Tom Seaver. The rudest was Dwight Gooden.
I've met most of the stars from Star Trek TOS and TNG over the years, and most of them were very nice. My favorite was DeForest Kelley, but I didn't get to spend as much time with him as I did with some of the other stars.
One of the nicest (and funniest) of the Star Trek stars was John de Lancie. He told some stories that had everyone
Gene Roddenberry came to a show and brought a 3-reel movie, but he only brought the first 2 reels. Nobody realized it until the second reel ended, and they realized that they didn't have the last reel. (It was a long time ago, so I don't remember much about the movie, but I think it was called either
Phoenix or
Genesis.) When he was answering questions later in the convention, he refused to tell anyone how the movie ended. (Most of us just assumed that he didn't remember.)
One comic convention was a tribute to the Sid and Marty Krofft shows of the 1970s. At the after-show party, I had great conversations with Jack Wild (
H.R. Pufnstuf) and Johnny Whitaker (
Sigmund and the Sea Monsters). They were both super nice.
Richard Dreyfuss is one of my favorite actors, and I was thrilled to meet him, but he's very opinionated sometimes, and he was talking a bit too much about politics at the time. He was much more fun to talk to when the conversation switched to baseball.
In a short conversation with Malcolm McDowell, I found out that he didn't like being in New York, but I think it had a lot to do with the (hot) weather at the time.
I met Stan Lee at a convention in 2012, and found out that he didn't collect anything related to any of the characters that he created. He said that the only thing he collected was (in his words) "pictures of dead presidents", (aka money).
He was supposed to appear at another convention in 2017, where he was going to officiate a wedding, but he had to cancel due to health issues. Sadly, he passed away about a year later.
