LOS ANGELES, Oct 3, 2007 (AFP) - Universal Studios is working on a fourth installment of its hit 'Fast and Furious' movie series, known for their spectacular car chases, Hollywood Reporter said Wednesday.

Actors Vin Diesel and Paul Walker, who starred in the first movie released in 2001, are set to resume their roles in the latest film of the series, which has been panned by critics but has won a cult following among fans earning some 600 million dollars at the box office.

The screenplay for the fourth film is so far top secret, but it will be directed by Justin Lin, a 34-year-old Taiwanese-American filmmaker, the magazine reported.

Diesel and Walker both starred in the first 'Fast and Furious' in 2001, and Walker appeared again in '2 Fast 2 Furious' in 2003. The third film 'Fast and Furious: Tokyo Drift' was released in 2006 and directed by Lin.
