We're less than a couple of months away from Game of Thrones  season four, but you can reunite with star Kit Harington on the big screen in Pompeii this weekend. While the time period and setting aren't crazily different than in Game of Thrones, we do at least get to see Jon Snow out of his furs and baring his abs. It can be jarring seeing the series actors in different roles, but it's fun nonetheless. Their other jobs are pretty diverse — do you know which ones are Harry Potter alums, Downton Abbey dwellers, or superhero blockbuster stars? Click through to see the Game of Thrones cast as you've never seen them before.

Cersei is hardly the first tough character Lena Headey has played; she was the title character in the short-lived Terminator: The Sarah Connor Chronicles on the small screen in 2008.
Look at that proper little English schoolboy! In the 2009 drama A Shine of Rainbows, Gleeson looks light years away from the sniveling, sociopathic king he plays on HBO. Maybe we just need to get Joffrey in more sweaters, and he'd be a little less crazy.
The beauty who plays Margaery Tyrell may look familiar to you, and not just if you used to watch The Tudors. Dormer also had a small part as a private in Captain America: The First Avenger.
Flynn plays fierce soldier Bronn on Game of Thrones, but did you know he's an equally fierce detective on the BBC? As Bennet Drake, he's helping to find Jack the Ripper in 19th-century England.
Rose Leslie doesn't have the most ladylike manners as Ygritte, but she certainly makes up for it as maid Gwen Dawson on Downton Abbey.
Who is this smoothly coiffed, smooth-dressing version of Peter Dinklage? He's gigolo Vinnie from the unmemorable Kate Hudson  movie A Little Bit of Heaven. Which is also Vinnie's nickname. I feel like Tyrion would think that was funny.
I can hardly remember a time when Jaime Lannister wasn't a grimy prisoner, so it gives me a little relief to see him in other roles. Especially where he's not so dirty, like in the 2009 TV movie Virtuality as a starship crew member. Look how nice he looks! I bet he even has two hands!
Dearly departed Ned Stark may be gone, but he's hardly forgotten. His portrayer, Sean Bean, has a prolific TV and movie career, and here he's seen as a pilot in the 2005 Jodie Foster  thriller Flightplan.
She was an important mother on Game of Thrones, and she also played the mother to an important wizard: Hermione Granger. If you don't remember her from Harry Potter and the Deathly Hallows: Part 1, it's because she's only briefly seen when Hermione is zapping her memory.
Hinds demands a lot of respect as Mance Rayder, but it might not just be about the character; the actor just oozes gravitas, like on last year's TV series Political Animals.
Yes, Game of Thrones boasts another Downton Abbey denizen: Iain Glen, aka Ser Jorah Mormont. On Downton, he plays Sir Richard Carlisle, who was formerly engaged to Lady Mary Crawley.
Did the season three addition of Jojen Reed somehow give you the warm and fuzzies? It should have, if you've watched (and rewatched) Love Actually — he plays young Sam, who loses his mum and falls in love in the same year.
Gendry got into some trouble as the bearer of King's blood on Game of Thrones, but he was getting into a different kind of trouble as Chris on the notorious British TV series Skins.
As Osha, Natalia Tena has been of great help to Bran and Rickon, and in the Harry Potter movies, she also helps out Harry and the gang as the colorful-haired Nymphadora Tonks.
He may be power hungry as Petyr Baelish, but Aidan Gillen actually possessed some power on another famous HBO series, The Wire, as Mayor Thomas Carcetti.
Khal Drogo is another gone-but-not-forgotten character . . . because who could forget those arms and chest? Momoa kept the physique but lost the scary warpaint and confusing facial hair for last year's Bullet to the Head, where he did battle with Sylvester Stallone.
You can't forget Mark Addy — as King Robert Baratheon, his character's death sets off much of the drama of the series. While Addy commanded respect on Game of Thrones, I can't help but LOL seeing him as Fred Flintstone in The Flintstones in Viva Rock Vegas.
Oh, man. I would love to hear what the dearly departed Robb Stark would say if he could see Madden's look in the 2010 TV movie Worried About the Boy as Boy George's companion Kirk Brandon.

Young Bran hasn't had the use of his legs since the season premiere of Game of Thrones, but happily, when the actor appears in other things, such as 2011 horror film The Awakening, he's walkin' around like nobody's business. Walk it out, Bran!
It's facial hair, furs, and cold weather for Kit Harington's Game of Thrones alter ego Jon Snow, so it's nice to see him in a much lighter ensemble in the 2012 horror film Silent Hill: Revelation 3D.
