In the close-up of the scoreboard before Richie's winning shot, it shows the visiting team leading 37-36. As Richie takes the shot, it shows them leading 70-69. Also, the scoreboard clock is already showing 0:00.
When Richie prepares to take the free throws "with one second remaining," the score is home 45 and visitors 46, with 14 seconds remaining. Potsie says he needs to make both free throws to send the game into overtime, when in reality, Richie's team would actually win. Then, before he shoots, Richie's team calls a timeout and the score is corrected for the plot, with it being home 45, visitors 47. Richie resumes, makes his first shot, misses the second, and his team loses, 46-47.
Donny Most's wedding ring can be seen.
Some of the statements that Potsie makes as he announces the game are obviously dubbed in later as his mouth doesn't move.
