"Stephen Amell: It's not that he pulls pranks. He's not like a prankster. It's not like all of a sudden I go put on the Arrow suit and it's filled with A535 or something like that. Although that would be pretty funny. It's more that there's just… You know, you've been to a panel? John's panels typically are called Anything Goes. Anything goes! Anything! John Barrowman gets away with more stuff than I've ever seen anyone get away with just because there's never a filter. So the expectation is: he really could be behind me right now. Would anybody be surprised? Exactly. He can always be around the corner. That's how I live my life. Barrowman is always standing behind me waiting to strike. Yeah, he's just a good guy. To pick your favourite thing or the funniest thing that John Barrowman has done is like picking your favourite flavour of ice cream. You can… but they're all so good! Why would you want just one? And to that end I've learned a lot of lessons from John. And I mean principally… I mean A) How to be the lead of a show. You know, he was the first guy that I really got to… I got to pick his brain. God, there's nothing I can say about him that can't be turned into something filthy. I hadn't been the lead of a show, so to hear about his experiences on Torchwood and then just in general to watch the way that he carries himself, to watch the level of respect he has for the crew, to watch the fact that his energy never changes, right? If they held a camera on John and we were on stage, I want you to tell me: is it ten o'clock on monday morning or is it four o'clock on friday morning? Tell me. You can't! 'Cause he's always the same. He always brings that same level of energy and professionalism and just joy to work and he carries that through with, you know, he and I hanging out in Palm Springs or we have these Con weekends. It's just great. I love John. I miss him."
