Jonah Hill and Channing Tatum are injecting a dose of Hollywood star power to Pocono Raceway.

Hill and Tatum were chosen as grand marshals for the NASCAR Sprint Cup race on June 8 at Pocono. They star in the upcoming comedy "22 Jump Street."

Both actors will give the honorary command to fire engines and take part in a VIP question-and-answer session.

Pocono Raceway president Brandon Igdalsky says Hill and Tatum add to the excitement of race day. Their appearance is a good get for the track, with the Hollywood heavyweights outshining the lower-tiered stars that appeared this year at the Daytona 500, among other races.
