About a year ago at this time, no one had heard of Emilia Clarke or Jack Gleeson. Peter Dinklage was best known as that short children's author who attacked Will Ferrell in Elf.
Fast forward to 2012, following a wildly-acclaimed opening season of Game of Thrones, and most of these actors/actresses are household names. In the case of Dinklage, they're even Emmy Award winners.
With season two kicking off on April 1, who will be joining these GoT stars on the small screen every Sunday night? Who might even take the Emmy stage in September? Below, we profile a handful of new Game of Thrones cast members. You'll be getting to know their characters very well over the coming weeks...
