The SAG Awards are this Sunday and Javier Bardem is up for a Best Supporting Actor as Raoul Silva in Skyfall. LA Times and Collider talked to Bardem about playing villians like Silva and Anton Chigurh in No Country for Old Men, which he won a SAG award for five years ago. "Chigurh was more of a statement of violence in the world, more of an idea but Silva is a man who had a very anguishing experience that he wants to fix, and that is more relatable to all of us."

Bardem also transforms his appearance in both roles, which often gets as much talk as his perfomances.

Your work cannot come from your's more about, how do I help this story by portraying the character as it needs to be, on every level, for this story to be told?...As actors we have the room to express as many sides of our nature as we are able or willing to show. There is no danger in can get lost, of course. You have to know how to come back. The difference between a person with mental problems and an artist is that only the second one has a two-way ticket.

Watch Bardem in clips from Skyfall and No Country and decide for yourself - who is the creepier villain?

Bardem on Silva.

He's this smooth, weird-looking blond person who wants to be perceived as this angel -- even if it's an angel of death -- because that's the opposite of how he feels inside.

From the haircut and all that? It's funny, because I saw that photo and I didn't pay attention to the haircut because it was more of the way he was dressed as well as anything, but I guess they [Coen Brothers] pay attention to the haircut. So, I went to the trailer and they cut it and I saw it and I said, 'What the hell is that?' But that helped a lot actually, because in a way he gave this reality to the character this dimension of being very methodical. Everything is in place. It's kind of mathematical. Like perfectly structured which is the way I thought the character should be. Perfectly clean. I thought this could help, but not for my private life though.

Bardem also won an Oscar for playing Chigurh in No Country for Old Men

No Country for Old Men is available on DVD, Blu-Ray and Digital Download.

The SAG Awards are this Sunday, January 27, 6ET/3PT on TNT and TBS.
