HBO promos give us a peek at new 'Game of Thrones' costumes

Hard as it is to believe, the characters on Game of Thrones are all part of one big old family: HBO. In a series of new promos featuring characters from all its original programming, the cable giant gave us a little tease of new Game of Thrones costumes, and the giant crossover show we didn’t know we wanted.

All three ads show characters laughing, singing, exhaling (and in the case of The Leftovers, smoking) until they match the the note that introduces every HBO show.

The good folks at Screencrush compiled all the Game of Thrones costumes into a handy little gallery, but you should watch the video promos for the full effect of everyone singing the same note (and Hodor contributing his usual two cents).
