Other mistake: Most evident in the massage scene, Jilly's gold ID bracelet on his left wrist is inscribed with the name "Jerry". Jilly is played by Jerry Weintraub.
Other mistake: In this film, the oldest son of Catherine and Eddie is named Denny. In the original film, his name was Dale. He looks the same (although a different actor used) so it's under the assumption it's the same kid.
Other mistake: When Rusty put coins into the slot machine to win the first car, he only put in 2 coins, but if you look closely at the payout table, he would have had to put in 3 coins to win the car. The same thing happened when he won the Viper. Also, when he won the Viper, the light on the top of the slot machine did not flash on and off, which would have happened if he had any type of big win.
