Next summer's Fast & Furious is not only the fourth installment of the franchise, it's also a momentous occasion: the reunion of original stars Paul Walker and Vin Diesel, who reprise their roles as undercover cop Brian O'Connor and criminal street racer Dominic Toretto!

After a 2003 sequel that starred Walker but not Diesel, and a 2006 prequel featuring a cameo by Diesel but not Walker, both are on hand for director Justin Lin's summer 2009 sequel. And they're not alone. Rejoice, as original Fast & the Furious hotties Michelle Rodriguez and Jordana Brewster also reprise their roles as the respective love interests of Dominic and Brian! Marvel as Sung Kang pops up as Han, the mentor to young racer Lucas in 2006's otherwise unrelated prequel, Tokyo Drift! Fast & Furious aims to fill in the gap between the second and third films, and will explain how Dominic and Han came to ride together once upon a time.

Official Synopsis:

Vin Diesel and Paul Walker reteam for the ultimate chapter of the franchise built on speed-Fast & Furious. Heading back to the streets where it all began, they rejoin Michelle Rodriguez and Jordana Brewster to blast muscle, tuner and exotic cars across Los Angeles and floor through the Mexican desert in the new high-octane action-thriller.

When a crime brings them back to L.A., fugitive ex-con Dom Toretto (Diesel) reignites his feud with agent Brian O'Conner (Walker). But as they are forced to confront a shared enemy, Dom and Brian must give in to an uncertain new trust if they hope to outmanuever him. And from convoy heists to precision tunnel crawls across international lines, two men will find the best way to get revenge: push the limits of what's possible behind the wheel.
