Agrand entrance, by helicopter, of Hollywood stars Jennifer Aniston and Gerard Butler in the morning. Six hundred extras acting as if there was a real race taking place at Monmouth Park. That was the scene last August at the Oceanport racetrack, where there was plenty of activity associated with the filming of a segment in the Columbia Pictures comedy "The Bounty Hunter" directed by Andy Tennant.

Released Friday, the film centers on a bounty hunter (Butler) hired to retrieve his ex-wife who has jumped bail (Aniston).

John Heims, the track's media relations director, was on hand during the filming to help producers arrange having horses and jockeys on hand to simulate racing scenes to the cheers of the extras.

"The movie people began setting up . . . started getting ready at 5 a.m. The filming started at 11 a.m.," Heims said. Other East Coast locations used in filming the movie include Atlantic City and New York.

This is not the first time for Monmouth Park on the big screen. The 1984 "Pope of Greenwich Village"with Mickey Rourke had scenes from the track. So did episodes from TV's "Law & Order" and "The Sopranos."

The participating jockeys in the racing scenes shot at the park included Luis Rivera, Felix Ortiz, Jose Velez, Pedro Cotto, Francisco Maysonett and Navin Mangalee, all regular riders when real races take place.

The horses were supplied by trainers by Ben Perkins Jr., Tony Wilson, Patrick Bottazzi, Luis Carvajal and others.

"The idea was to have eight horses go to the starting gate, come out of the gate and run for about 70 yards, with crowd scenes," Heims said. "It took a good part of the day."
