Jack Huston, 26, who is Anjelica Huston‘s nephew and the grandson of famed director John Huston, has been cast in The Twilight Saga: Eclipse as Rosalie Cullen’s former fiancé. For those of you who haven’t read the books, Rosalie (Nikki Reed) is Edward’s (Robert Pattinson) adopted sister. Before she became a vampire, when she was a young woman during the Great Depression, she was engaged to the very rich and handsome Royce King II, before her life took a tragic turn. Huston has appeared in films such as Factory Girl starring Sienna Miller and Shrink starring Kevin Spacey. The role in Eclipse will be his most high profile to date. Earlier this month it was announced that Bryce Dallas Howard, director Ron Howard‘s daughter, would be taking over the role of Victoria, a vampire who’s out to get Bella (Kristen Stewart). [Poll=128]
