When I watched this video, I learned how to correctly pronounce his name. It's not Gatiss, it's pronounced G-A-tiss. You actually say the "a".....
MARK GATISS, a British actor, comedian, screenwriter and novelist. - played in The Game of Thrones as Tycho Nestoris. He also did TV series Dr. Who and Sherlock. A member of the comedy team, The Leagues of Gentlemen.
Mark Gatiss, Benedict Cumberbatch, Louise Brealey, Andrew Scott, Una Stubbs and Rupert Graves
Mark Gatiss is the biggest shipper of Johnlock ever in the universe and he writes the show, that means he's in a place of ultimate power, and that scares me. I'm going to say something I never thought would make any sense. Save us, Steven Moffat. Save us from the maniacal writing of Mark Gatiss.
