The racehorse owners say their horse is running on Saturday, yet the day of the race Trotter opens the Daily Racing Form dated Wednesday, January 25th, 1989.
Trotter is handcuffed behind his back when he makes a dash for the betting window. When he is tripped, and slides on his stomach across the floor, you can see his hands (briefly) uncuffed.
In the opening sequence in the cab, the cab driver, David Johanson's cigarette goes from freshly lit to a small butt back to a new cigarette, all in a couple seconds.
In the race he has the #3 horse, the lanes the horses are coming down the stretch change. The #4 is on the rail, then a couple seconds later is impossibly in the 3rd lane from the rail. This occurs multiple times thru the movie.
When Trotter makes the big bet on the last race, we see the odds drop from 40-1 to 8-1. A bet that size would have increased the odds on every other entry the moment it was bet, but none of the other numbers change.
The movie takes place on a Saturday, but the NFL game is shown on television screens in the Jockey Club. Looney's bookie comes to collect on the $850 he lost on the game. NFL games are not played on Saturdays except, occasionally, in December. There is a reference from Trotter's wife that it is September.
A contributor stated that Trotter would have won $1,420 on the first race. No, the script is correct. A $50 win pays 25 x the $2 win payoff , or $710.
Trotter bet $50 and won at 28.40. He would've won $1,420 in the first race.
The cashier calculated the potential winnings from the last wager on the odds BEFORE the bet. A wager that size would have made the horse the odds-on favorite resulting in a profit of just the minimum payoff of five cents on the dollar.
