Casting Suggestions For How to Be Single

On-and-off BFFs Diaz and Barrymore first appeared together in Charlie's Angels, but they haven't been reunited since that movie's sequel. Here's their opportunity: Diaz could play Serena, Julie's blond, lithe friend Serena, who finds love when she's in search of spiritual enlightenment. The character of Serena becomes a swami at one point and shaves her head, something Diaz was comfortable doing (or faking, anyway) for her role in My Sister's Keeper.
