Somehow this one slipped by us this week – Robert Downey Jr. officially jumped ship on Alfonso Cuaron’s outer space survival thriller Gravity, and has moved on to producing and possibly starring in How to Talk to Girls, a film based on a book by 9-year old Alec Greven. No ink has been committed to paper just yet, but sources say that Downey is circling the project with great interest. Shawn Levy, who is also slated to produce, has said that the script (written by Ben Karlin and Stu Zicherman) is in the tone of Big. And anything “in the tone of Big” is worth paying attention to, even if it was written by a 9-year old. [THR]

Fox just picked up an option to adapt “How to Talk to Girls,” a book written by a 9-year old. We wonder how that makes all of the waiters and bartenders in Los Angeles feel…
