The scene where Joe Pesci jumps out of the stands to give Billy Popfinger a beating after blowing up his bet (with Popfinger planting his feet in the ground to prevent his horse from winning) is classic. Come on now; haven't we all secretly wanted to do that to some driver after a questionable or bad drive? LOL.
P4, that is the best racing moment IMO. It's not the best racing movie however. Runner up for moment is in "Goldfinger" when the FBI is mistaken for tipsters at his trotter farm in KY. The farm they used in the movie was immaculate and the horses looked like champs warming up on the training track. Someone should write a funny movie about harness racing a la "Let It Ride". TC
