Trivia: The infant playing Connie and Carlo's baby son Michael Francis Rizzi who Kay holds during the christening scene is Sofia Coppola, Francis Ford Coppola's daughter, who was born in May 1971. Sofia later had a prominent role in Part III as Michael's daughter, Mary. Other than the main characters, Sofia is the only actor to have appeared in all three films. In The Godfather II, she can be briefly seen as an immigrant girl on the ship that brings Vito Corleone to Ellis Island.

Trivia: In the scene where Alex approaches the two girls at the record stand you can see the original score for 2001: A Space Odyssey, also directed by Stanley Kubrick.
Suggested correction: The album shown in the picture is NOT, as is commonly believed, the soundtrack of 2001, but rather a compilation of movie theme music that includes the main theme of 2001. However, the ACTUAL soundtrack of 2001 is still visible in the scene, just a little earlier: When Alex finishes flipping through a magazine and tosses it down on a counter, one of the records in that shot is the 2001 soundtrack.
Trivia: Christian Bale dropped approximately 60 pounds for the role, going from 180 to 120, by eating a diet of one can of tuna and an apple a day for months. This is the most weight ever lost by an actor for a film role. Within 6 months of this film he then put on 100 pounds to play Batman in Batman Begins. He actually gained so much weight he was too big for the batsuit and had to drop 20lb for filming.
Trivia: When Mr. Jimmy is calling out names on the boat to see who's missing, the real Mr. Jimmy Harrell is standing next to him, wearing a dirty grey T-shirt (and presumably playing a random rig worker). You can first see him (from the back) when Russell calls out Caleb Holloway's name. The first view of his face is just as Russell gets out the life raft onto the deck of the rescue ship. (01:28:30)
