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).

Trivia: In "Split", James McAvoy was filming a scene with the multiple personalities talking amongst each other, and he punched a door that broke his knuckle.

Trivia: Spoilers: There's a pretty subtle bit of foreshadowing in Gary's house. When he's seated and the group is playing Jenga, if you look behind Gary, there are two old-fashioned guns on the mantle. The way the shots of Gary are framed throughout the scene, both guns are pointed right at him several times. Later in the movie, Gary ends up being shot twice by two different guns - once by a gun loaded with blanks and once by a gun loaded with live ammunition.
