Dunno if he qualifies as an A lister, but Rhys Darby (Jumanji, Yes Man) and I got to know each other when he was doing stand up in New Zealand. He is a seriously funny guy, and so giving and humble with his time. Had a few post gig beers with him one night, him, me and two other NZ comedians in a booth at the Classic Comedy and Bar in Auckland. Still one of the best nights I ever had. Great guy!
