Untitled motocross movie: According to Variety, Paramount Pictures is revving up a coming-of-age film about James "Bubba" Stewart, a teen who is to motocross racing what Tiger Woods is to golf.

Michael London will produce with C/W partners Tom Cruise and Paula Wagner.

The film is being written by David Gordon Green ("George Washington") and will mark the feature directing debut of celebrity photographer Sam Jones.

Taught by his father to ride before he could walk, Stewart was winning titles by the time he was 7, and at 16 became the first African-American to win a major motorsports title. He has so dominated the 125cc division that he's been known to lay down his bike during a race to let competitors catch up.

Stewart faces his biggest test Saturday in Anaheim, when he steps up to the 250cc supercross class and takes on the division's dominant champ, Ricky Carmichael. Producers are scrambling to have cameras ready to capture footage to be used in the film.
