Deadline says Travolta will play Dennis, a burned out DEA agent, Lively is set to take on the role of O, and Thurman would play her mom, named Pagu.
In the book, two friends from Laguna Beach (Aaron Johnson, Taylor Kitsch) share the same girlfriend (Lively) and a thriving business growing and distributing the best-quality pot on the planet. When they resist being muscled by a Mexican drug cartel, the girl is kidnapped and the ransom is every cent they’ve made for the last five years. They agree to pay but hatch an alternate plan to get her back, get revenge, and then get lost.
Salma Hayek will play the role of Mexican cartel queen-pin Elena and Benicio Del Toro is portraying vicious cartel enforcer Lado.
The Universal Pictures release is scheduled to start filming in July.
