It’s in Wikipedia. That’s all I know.
The movie itself is special. This is Martin Scorsese at his finest.
The movie does have one Guiness Book of World Records type scene. It might be my single favorite movie scene. Henry Hill (Ray Liotta) is on his first date with Karen (Lorraine Bracco). He takes her to the Copacabana.
From the time they leave their car until Henny Youngman comes on stage is around 3:00. Scorsese does it in one intricately choreographed single shot. No edits. No stops. Amazing.
The long tracking shot through the Copacabana nightclub came about because of a practical problem: the filmmakers could not get permission to go in the short way, and this forced them to go round the back. Scorsese decided to film the sequence in one unbroken shot in order to symbolize that Henry’s entire life was ahead of him, commenting, “It’s his seduction of her [Karen] and it’s also the lifestyle seducing him”. This sequence was shot eight times. – Wikipedia
