Rachel Weisz says she's excited to work With Robert Pattinson.
"The ironic thing is, RPattz’s co-star, Oscar winner Rachel Weisz, has plenty of details to dish about the drama but knows virtually nothing about “Twilight”.
“Meeting him was vampiric. He sucked my blood,” laughed Weisz, remembering their introduction. “Wait, is he the vampire? He is the vampire, right?”
And in “Unbound Captives”, Pattinson is eager to portray a teen living in the Western frontier who was kidnapped by Comanche warriors at a young age; Weisz is slated to play the mother on a mission to get her son back. Co-starring alongside Hugh Jackman, Pattinson told us recently that “Captives” offers him a character who “can’t really be more different from Edward,” the leading man of “Twilight.”
“It’s an independent movie, and they are raising the money, so hopefully it’ll happen”, Weisz said of the flick, which will mark the writing and directing debut of veteran actress Madeline Stowe. “I don’t know if it will [be made], but yeah, I’m very excited".
“It’s a great screenplay, and [Pattinson and Jackman] are both great actors,” Weisz added of why she is attached to the film. 
Rian Johnson with Rachel Weisz at "The Brothers Bloom" TIFF Press Conference on 9th November 2008.“I like to work with all kinds of talented people, whatever the age.”
Weisz — who can be seen later this month in director Peter Jackson’s drama “The Lovely Bones” — said another reason she’s eager to work with RPattz is his mystique.
“He wasn’t star-struck. He’s got a whole rebel vibe, right? Yeah, that was his vibe,” she said of their meeting. “He’s kind of iconoclastic. He’s flaunting authority. Yeah, pretty cool.”Source: robert-pattinson.net
