Season Three of "Game of Thrones" is coming ... and soon!

HBO just released 23 new photos from the upcoming episodes, showing all of the main characters in action and a few brand new faces.

We've got Jon Snow (Kit Harrington) trying to keep warm on the other side of the wall, the nasty King Joffrey (Jack Gleeson) teaching his new squeeze how to shoot and Daenerys (Emilia Clarke) minus her dragons ... but with an entire army!

And while there are also shots of returning favorites like Tyrion, Arya and Melisandre, it's one of the new characters that really caught our attention: Thomas Brodie Sangster as Joien Reed (right).

Thomas, of course, played Liam Neeson's son in "Love Actually" back in 2003.

Hard to believe that movie was made 10 years ago ... and Sangster is now 22!
