Watch: The Trailer for 'Game of Thrones' Season Three Promises Vengeance and Dragons

There be dragons in the trailer for "Game of Thrones" season three, below, as well as flaming swords, funeral pyres and armies in array.

The preview for the upcoming season of HBO's hit fantasy series, which returns to the air on March 31st at 9pm, was premiered last night on "Jimmy Kimmel Live!" before being released online.

The trailer's only a minute, but packs in looks at everyone's favorite characters, from Tyrion (Peter Dinklage) to Arya (Maisie Williams) to Daenerys (Emilia Clarke). It also makes a solid case for the series as having a scope and production value equal to that of a studio film.
