An all-star cast is coming together for Oliver Stone's drug cartel drama "Savages."

John Travolta and Uma Thurman, who starred together in "Pulp Fiction" and "Be Cool," are in talks to join the cast. Also in discussions to co-star is Blake Lively ("The Town"), according to Deadline.com.

Variety is also reporting that Emile Hirsch ("Milk," "Speed Racer") is coming on board as well, although his role in the film has yet to be revealed.

They will join already-announced cast members Taylor Kitsch ("Friday Night Lights"), Aaron Johnson ("Kick-Ass"), Salma Hayek and Oscar-winner Benicio Del Toro.

The film, based on Don Winslow’s bestselling book, centers on two small-time pot dealers (Kitsch and Johnson) who are bullied into aligning themselves with a violent drug cartel (Del Toro will play a brutal enforcer) after their close friend, O (Lively), is kidnapped. Travolta will play a DEA agent on the case, and Thurman will play O’s mother.

Writer Winslow penned the script with Shane Salerno ("Aliens vs. Predator: Requiem").

Stone's last film was "Wall Street: Money Never Sleeps," with Michael Douglas and Shia LaBouef.

"Savages" will start shooting in early July. Universal Pictures will finance and distribute the film.
