"We do our one last job and then we disappear.. forever!" -Dominic Toretto
So.. We thought that was the end of The Fast & The Furious movie series.. Sad to hear, Right? BUT ...
In a post-credit scene of Fast Five, Hobbs is given a special file by U.S. Customs agent Monica Fuentes (Eva Mendes) concerning the hijack of a military convoy in Berlin. In the file, Hobbs discovers a recent photo of Leticia "Letty" Ortiz (Michelle Rodriguez), Dom's presumed-deceased girlfriend, revealing she survived the events of Fast & Furious, leading to the thought of a possible sequel. Vin Diesel and series producer Neal Mortiz are already developing the sixth film Fast & Furious 6, which will be written by Chris Morgan. Director Justin Lin stated in an interview that he intends to get Vin Diesel, Paul Walker, Dwayne Johnson and Tyrese Gibson back as well as others. On June 24, 2011, Vin Diesel revealed on his Facebook account that the release date for Fast & Furious 6 is Memorial Day (May 27) 2013.
