HBO debuted the first trailer from Game of Thrones: Season 3 on Jimmy Kimmel Live! The minute-long clip features a voiceover line from Ser Jorah Mormont, "there's a beast in every man and it stirs when you put a sword in its hand." An additional line,” the revenge you want will be yours in time," is also featured. The Khaleesi, and her new army, are also featured — along with her flying dragons as she makes her way toward King's Landing and the Iron Throne. Game of Thrones: Season 3 premieres Sunday, March 31 at 9:00 p.m. (EST) on HBO and HBO Go.
