From The Hollywood Reporter‘s Heat Vision blog, word that Olivia Wilde is deep in negotiations to join Daniel Craig in the sci-fi western Cowboys and Aliens, which Jon Favreau is directing for DreamWorks. Wilde would play a character named Ella, who joins up with mysterious gunslinger in an unlikely uprising against an alien invasion; Craig is playing the gunslinger, taking over the role from Robert Downey, Jr., who dropped out in January to jump into a fast-tracked Sherlock Holmes sequel. This would be good news for fans of alluring eyebrows, no doubt.
