Revealing: At the beginning of the film where Robert De Niro gets into his car and it explodes, you can clearly see the cut where they have replaced him with a dummy.

Continuity: When Joe Pesci is beaten and then buried - look at the blood on his chest. In one shot it is all over - the next it is just a smaller patch.

Continuity: When Remo Gaggi is talking to Andy Stone about Ace cussing out the Board, there's a pack of cigarettes beside Gaggi in his car.  The camera angle changes to show Stone's face, who is outside the car, and when it flips back to Gaggi, there is a Zippo lighter in place of the cigarettes.  The camera goes back to Stone, and when it comes back again, the Zippo is gone and the cigarettes are back. And to top it all off, not once did Remo smoke in this scene.

Revealing: When Sharon Stone gets thrown out of Joe Pesci's club, you can clearly see the pads on Stone's hand's to break the impact of the fall.

Revealing: In the scene where Joe Pesci is beaten in the corn fields, if you look closely at the bats you will see them bend ridiculously on impact with his body. Foam bats anyone?
