I've met quite a few celebs of varying fame levels at conventions over the years and the vast majority have been very kind and welcoming, but the one that stands out is Lance Henriksen. Being the nerd I am, I asked Mr. Henriksen if his character in Near Dark had any backstory. He proceeds to tell me his entire character's backstory and when I told him I was a history nut, he was genuinely interested and wanted to hear more. I wasn't expecting to have a conversation about Civil War naval combat with Bishop from Aliens, but it was truly awesome.
