Casting Net: Kristen Stewart in talks for a sci-fi love story

• Felicity Jones may have helped put director Drake Doremus on the map with her affecting performance in his lovely indie Like Crazy, and then again in Breathe In, but Doremus is eying a new heroine for his next project: Kristen Stewart. The director is reportedly courting the Twilight star and Nicholas Hoult (Warm Bodies) for Equals, a science fiction love story. Moon scribe Nathan Parker wrote the script. [Deadline]

• Will Smith is reportedly attached to star in the 20th Century Fox thriller Selling Time about a guy who is given the option to add seven years to his life — as long as he agrees to go through his worst day once more. No director is attached to the long-gestating project (Smith was actually first attached years ago, as was Tom Cruise). Eagle Eye scribe Dan McDermott wrote the first version of the script, and Spike Lee, and Derick and Steven Martini have all written versions as well. [The Wrap]
