If the prospect of seeing Indiana Jones (Harrison Ford) and James Bond (Daniel Craig) dressed up as cowboys and fighting aliens isn't enough to entice you to go see director Jon Favreau's follow-up to Iron Man 2, Cowboys and Aliens, here's a little something extra to sweeten the pot: Olivia Wilde has a nude scene. (Okay, it is a PG-13 movie, so she's not going to be totally nude, but still.) In a recent interview with MTV in support of the movie, Wilde talked about how "crazy" it was to bare all on set, and also called "BS" on one aspect of Favreau's recreation of the Old West.

Wilde said that, while it was uncomfortable, it was "an honor" to film the "sexy campfire scene" because it is a "cool, climactic moment" in the movie.

"It was really exciting because we knew we were creating something kind of spectacular in that scene. It was a really cool effect happening, as people will see. It was kind of strange because I was half-naked in front about a hundred people, including the crew, a bunch of Apache warriors, a bunch of cowboys, and Daniel Craig, who I had to stand in front of basically naked. And he had to take a moment to sort of look me up and down before covering me in a blanket. And I was like, this is crazy."

Wilde also said that some of the dirt on the actors was not applied by makeup artists, but was a natural result of shooting in the desert, and pointed out that, for true authenticity, the actors shouldn't have all had nice teeth.

"We were literally dirty because we were riding all day long out in the desert, and you get very dirty. But the dirtier everybody looked, the hotter they looked. It was a really good look, I think. ... The people in the Old West were very dirty. The thing that's unrealistic about our movie is all our teeth: We have good teeth; they didn't have good teeth. So, logic police will call BS on that."
