Vin Diesel, who stars in next Friday's Babylon A.D., told ComingSoon.net today that he is directing a 20-minute prequel to Fast and Furious, the fourth installment in the Universal Pictures franchise.

Diesel will star in the prequel along with Michelle Rodriguez reprising her role as Letty and Sung Kang returning as Han. Diesel didn't say how the prequel would premiere; it could be on a DVD, online, TV, etc.

The fourth movie is a sequel to the first installment, and though Diesel didn't elaborate, we assume this 20-minute prequel will tie-in some of the events from the second and third movies. Rodriguez appeared in the first movie, Sung Kang in the third, and Diesel in the first with a brief cameo in the third.

In the Justin Lin-directed Fast and Furious, opening June 5, 2009, fugitive ex-con Dom Toretto (Diesel) reignites his feud with agent Brian O'Conner (Paul 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.
