HBO has released a third trailer for Game of Thrones Season 3 leading up to the premiere on Sunday, March 31. The 1-minute trailer titled “The Beast” teases you with some footage of Catelyn Stark (Michelle Fairley), Jon Snow (Michelle Fairley), Theon Greyjoy (Alfie Allen) and Daenerys Targaryen (Emilia Clarke) leading the Dothraki to war. Season 3 wouldn’t be the same without the Lannisters, as Cersei (Lena Headey), Tywin (Charles Dance) and Tyrion (Peter Dinklage) return to the series.
