Curtis "50 Cent" Jackson, Ellen Barkin, Kiefer Sutherland, Chace Crawford, Emma Roberts and Rory Culkin have signed on to star in Joel Schumacher's "Twelve."

Based on the novel by Nick McDonell, the film centers on a former high schooler and drug dealer whose life takes a drastic turn after his best friend is arrested for murdering the dealer's cousin. Jordan Melamed wrote the screenplay.

Schumacher most recently directed "The Number 23," which I admit I pretty much hated. His credits also include "The Phantom of the Opera," "Veronica Guerin" and "Bad Company."

Jackson last starred in "Righteous Kill," and he's got plenty of future projects lined up. Roberts was recently seen in "Hotel for Dogs," while Barkin last appeared in "Ocean's Thirteen." As for Crawford, he's been busy doing "Gossip Girl."

Culkin's credits include "Signs" and "Mean Creek," and Sutherland is still running around as Jack Bauer. He also voiced a character in "Monsters vs. Aliens."
