9. Copacabana Tracking Shot - Goodfellas
In Scorsese's inimitable classic, mobster Henry Hill (Ray Liotta) takes Karen (Lorraine Bracco) to the Copacabana club, and in order to fix a practical issue - the club's owner wouldn't let Scorsese bring a camera through the front - the scene unfolds as a seamless pass through the back of the club, out of the kitchen and onto the main floor, where Karen is subsequently seduced by the overwhelming power of Henry's success. It's one of the most popular tracking shots in movie history, largely because there's so much going on and so many moving parts to consider, from the hundreds of extras milling about in the background, to setting up that table quickly.
