Characters yet to be cast:

Melanie - Caswell's fiancee, the love interest.

Bill Caswell's Mom - The lovely lady that let Caswell build his rally car in her Chicago garage.
Paul Donlin - Friend of Caswell, co-drove in rally Colorado.
Evil WRC official - There has to be some kind of antagonist, right?
Roberto Mendoza - Opposite of Evil WRC Official. He's the WRC guy who helped Caswell get into the race.
Pedro Mooninite - The guy who moons Caswell on day three. (By the way, this is our bet for the Caswell cameo)
Sam Smith - The guy who wrote the story but didn't actually believe in it... even though he helped build the car.
Ray Wert - The editor who believed in the story but didn't actually write it... and is only on this list because he signs the paychecks.
