'Hansel & Gretel' Hotties: Cue the Incest Jokes!

Hansel and Gretel are getting down to business… Hot off The Bourne Legacy, Jeremy Renner teams up with former Bond girl Gemma Arterton (against former 007 villainess Famke Janssen) for the decidedly different shoot-'em-up thriller Hansel and Gretel: Witch Hunters, and the pair joked about their on-camera brotherly-sisterly bond for ET.

"For me it was the brother-and-sister duo, thing," says Gemma. "It's really rare to have that, and they're both as bad-ass as each other, and they need each other, and there's all that emotional backstory with them as well, and it really roots the whole thing because it's a fantasy film."

When ET's Brooke Anderson tells the pair that they look like they could be brother and sister, Jeremy replies jokingly, "Alright, so we shouldn't make babies, then? That would be weird, right?"

In theaters January 25, Hansel and Gretel casts Jeremy and Gemma as the title fairytale characters – only this time, they're all grown up and making up for that "traumatic gingerbread-house incident" that went down when they were just kids. Armed with an arsenal of medieval weapons and playthings, Hansel and Gretel focus their efforts on taking down a variety of supernatural creatures and a new, evil witch (Janssen) who is kidnapping children. Not on their watch!
