'Game Of Thrones' Premiere: The Secrets Behind Red Viper's Sexy Debut

Pedro Pascal has it his way in his first scene on 'Game of Thrones.'

When it comes to Oberyn Martell, it's his way or the highway — and the highway's closed.

Chilean actor Pedro Pascal made his Westeros debut in the "Game of Thrones" season four premiere, stepping into the highly anticipated shoes of the Red Viper of Dorne. The Dornish prince has come to King's Landing under the pretense of attending King Joffrey Baratheon and Margaery Tyrell's upcoming nuptials. In reality, Oberyn wants something else entirely: every Lannister's head on a silver platter.

Beyond vengeance, Oberyn desires something simpler: a good old fashioned roll in the hay at Littlefinger's brothel. Oberyn and his paramour, the Dornish noble-born bastard Ellaria Sand, hire one of Littlefinger's prostitutes, as well as the "procurer" Olyver, to get tied up in a Meereenese knot all their own. Just like Oberyn himself, Pascal wasn't nervous to film his character's sexually-charged debut.

"It was just fun. It was a lot of fun," Pascal told MTV News about the Red Viper's debut, alongside actress Indira Varma as Ellaria. "It wasn't the kind of environment that makes you feel self-conscious. Everybody was really supportive. And obviously, the kind of stuff that they've already shot on the show is pretty racy. You just come into the fold and become part of it. I had a good time."

"Game of Thrones" is all about fire and blood, and clearly, the Red Viper has both sides of that equation on lockdown. Not only is he in command of his fiery passion, he's also deadly with a blade — especially when he has the chance to turn the tables on the Lannisters and all of their supporters.

"[If you have] the last name 'Lannister,' you're on my bad side," Pascal explained. "I hate you."

Why does he hate the Lannisters so much? It might have to do with the fact that when they sacked King's Landing on the last night of the Mad King's reign, the Lannisters and their loyalists brutally murdered Oberyn's sister Elia, wife of Rhaegar Targaryen. As such, Oberyn wants his pound of flesh.

But does Oberyn hate every Lannister? He seems to get along well enough with Tyrion, the impish outcast of the Lannister family. By virtue of Tyrion's last name, Oberyn doesn't love or trust the man — not yet, at least. That could change based on future interactions.

"Oberyn is a defender of the underdog," said Pascal. "I think it's inevitable that he recognizes a kindred spirit with somebody who has the kind of wit, sharpness and resilience of Tyrion."

"They've known each other since they were children," he continued. "That's an exciting thing to play with. 'You're in the family that represents everything I hate, that I want to come after pretty hard — and yet, you're cool. You and I would probably be buddies.'"
