Trivia: Have a close look at the Predator's trophy collection on his spaceship. Taking pride of place is a skull from the creature in the Alien movies. (01:33:05)
Trivia: The entire "How am I funny?" scene was improvised by Joe Pesci and Ray Liotta.
Suggested correction: False. Joe Pesci told the anecdote to Scorsese in the earliest stages of the movie. Scorsese asked him to add it during previous script readings and further rehearsals while notes were being taken by crew members. Then it was finally shot following those rehearsals and notes. In this video all the actors involved tell how Scorsese works and even he himself says he rewrote that scene 4 times. Minute 13:04: https://youtu.be/_bbzUZuxEB8.
I have actually seen interviews where they admitted it was improvised. The reactions from the other actors was genuine.
Trivia: When Kevin is in Buzz's bedroom, he finds in the box a picture of Buzz's girlfriend. This is actually a picture of the art director's son dressed up to look like a girl, because the director, Chris Columbus, thought it would be too harsh to make fun of a girl like that.
