Ah, San Diego Comic-Con. The time when the nerd wheat is separated from the nerd chaff. Especially when the celebrities that now flock to the convention stop by and come face to face with MTV News.
We continued our annual tradition of peppering celebrities such as Maisie Williams, Tyler Posey, Dylan O'Brien, and many (many!!) more with trivia questions and requests for impressions in our game of Geeks or Poseurs. Want to see if Bill Murray knows how to do the "Mockingjay" whistle? Of course you do! How about whether the cast of "Teen Wolf" can correctly ID the Indominatus Rex? And, of course, it's never a bad idea to see if anyone can correctly guess the height of the Boy Who Lived himself, Daniel Radcliffe.
Bonus points: Radcliffe's reaction to finding out that we'd been asking everyone how tall he is. Yeah, it's in there.
Check out the video above to find out who was a geek at this year's Comic-Con and who was a poseur.
