Julia Roberts, who first made her name playing, well, a hooker, continues to use her box office mojo to secure more assertive parts: The actress/mother will be both starring in and producing the film adaptation of the upcoming novel Hothouse Flowers, playing "a divorced woman who chucks her career at a New York advertising agency and sets out on a new adventure," according to the Hollywood Reporter. (Hopefully, that "new adventure" also involves a guy 2/3 her age.) Another red-headed "Julie" in the Tinseltown trades today? Julianne Moore, who will head up the supernatural horror film Shelter, reports Variety. Although the plot of the film has yet to be released by producers, it it's safe to say Ms. Moore will have to spend at least a few hours in the voiceover studio perfecting her scream. [UPI, Variety]
