The stars of "Transformers: Dark of the Moon" -- Josh Duhamel, Rosie Huntington-Whiteley and director Michael Bay -- will serve as the Grand Marshals for 53rd running of the Daytona 500 on Sunday. As Grand Marshals, the "Transformers" cast will deliver the four most famous words in motorsports -- "Gentlemen, start your engines."

In addition, the modified NASCAR stock cars featured in the movie will make their first public appearance by leading the 43-car field during the pace laps of "The Great American Race," the kick-off event to the 2011 NASCAR Sprint Cup Series season.

"We're honored to have the stars and director from this blockbuster film franchise 'Transformers: Dark of the Moon' serve as Grand Marshals of 'The Great American Race,'" Daytona International Speedway President Joie Chitwood III said. "As an added bonus for our fans, three cars from the movie will be on location during Speedweeks and we all look forward to watching them lead the field for the 53rd running of the Daytona 500 on the newly paved racing surface."
