Corrected entry: When Vince was playing Grady in the Atlantic City tournament, Grady misses the eight ball in the side pocket while the seven ball is visible on the other side of the table. Grady should have been shooting the lowest number ball on the table.
Corrected entry: At the end of the movie Vince and Eddie "lag" for the break. Vince wins the "lag" but Eddie breaks the balls.
Correction: There's no indication Vince won the lag, the camera pans out to specifically not show where the balls ended up. However, Eddie's smirk, cue pointing toward his ball and statement of "Just don't put the money in the bank, kid" - combined with Vince picking up his ball without complaint... it's pretty clear Eddie won the lag.
Corrected entry: In his first match-up with Grady Seasons, Vince is seen making the same shot two times during his games.
Correction: The cue ball moves in a slightly different way after making contact with the chosen ball, so it is two different shots.
Correction: Grady missed the 6-ball, not the 8-ball. Thus, it was a valid shot.
