Not gonna lie, Samuel L. Jackson is like dad levels of nice to you

Like a nice dad sort of way.

George Takai is a genuinely nice guy. My wife and I were at Planet Comicon in Kansas city last year when he was there, and his line was empty. We were getting his signature for my brother-in-law who is a big Trekkie.

We were expecting the standard shuffle through and signature experience, but he stood up, shook both our hands, and then just talked with us for what seemed like 10-15 minutes, but was probably only about 2.

We talked about his musical and when it was coming to the Midwest, and about his daughter's first job in Iowa, but how she missed the California weather.

He was the highlight of the convention for us.

A few years earlier, at the same con, my wife met Levar Burton. She is a librarian so had a "Read" poster of him from several years back.

She told him how when she was getting ready to move across the country to start grad school the Reading Rainbow episode about the Library of Congress came on, so she took that as a sign that she was making the right move.

He got up and gave a her a big hug, which of course drove the Star Trek fans mad.

Both of those guys are class acts, and really love their fans.

Harrison ford.

Neil Patrick Harris and Nathan Fillion among others.

Bryan Cranston.
I met him once in an audio recording immediately after Breaking Bad He came in, told a short funny story which broke the tension. Then he shook everyone's hand while greeting them. After the session he signed a hazmat helmet that a producer wanted to give as a wedding gift (bride groom were huge fans). He was also phenomenal in the booth nailing the script and making it his own. A+ all around.

Through a strange series of events, my dad became friends with Mike Tyson for a few months. This was fairly recent.

He came to our house a few times and we got to go to his house once. I would describe him as humble, funny, and genuinely nice. He never wanted to talk about his own boxing career.

One time he just popped in because he was nearby and didn't want to sit in traffic. Another time my dad asked if he would circle around and wave to our neighbor across the street who was outside. Instead he walked over and talked to the guy for a couple minutes.

He seems to have either been really busy lately or just moved on because he doesn't call or come over anymore.

John Waters.

The dude is over 70 years old, and he's still touring doing spoken word stuff. He gave one of the most entertaining and hilarious speeches of all time, and then as the show was ending just said "I'm going to be up here signing books afterwards so stick around."

You could tell he was exhausted after, as it was pretty late. Sure enough, hundreds of people lined up to get their books signed, and an attendant was there to grab your phone and take your picture with him. He was such a good sport and made small talk with nearly every person.

I had bought pre-signed books before the show because I didn't know he'd be doing this after, and he offered to personalize them for me anyway. I recommend watching his spoken word special on Netflix if you haven't seen it already. He's an amazing man.

Mark Hamill is a genuinely good guy. I worked in a Warner Bros. Store in NYC while I was in college, and we got word one day that he would be coming by with his family, and to make sure any needs he had were met. (Since he voices The Joker, he was a WB VIP) He came in, and stayed in my area for a while. (The floor I worked on sold animation cels and collectibles, and he was really into that stuff.) He was just beaming, happy to talk to people, shake hands, etc. Everyone had to be professional, but we were all smiles, too. The only thing he asked for while he was there was water. Really....I cannot stress how wonderful and nice he is.

I don't know if they count as a celebrities, but I got drunk in bar with Mark Millar (comic book writer, creator of Kick-A*s and Kingsmen) and Tony Harris (Comic Book artist, Starman, Ex Machina) They were in town for a signing at a comic shop, and then invited everyone to go drinking after it was done. Both fun guys. Mark Millar bought me whiskeys & cokes. After we left the bar, they were going to karaoke, but stupid me, I declined the invitation. I still regret that.

Ive heard many stories about Robin Williams being really kind and supportive to other people in the entertainment industry. Plus he named his daughter Zelda.

Steve Buscemi, from what I've heard.

Tom Hanks is notorious.

I met Bill Murray once and asked for a picture. He responded with "Who the hell do you think you are?". I kind of had a shocked look on his face and he finally told me he was kidding, gave me a handshake/bro-hug and took a picture with me.

About what I expected, and I'm damn happy with that.

KEANU!
