"The Crossing" premieres Sept. 30 on NASCAR.com. The five-episode documentary follows Gordon and Howard as they learn what it takes to be successful in the other's respective field.
The series was created and produced by NASCAR productions.
Howard's current project is the Formula One thriller "Rush," chronicling the tense 1976 world championship battle between playboy James Hunt and calculating Niki Lauda.
Gordon privately screened the movie for his Hendrick Motorsports team over the summer as a bonding experience for his crew.
