Trivia: The Klingon who defends Kirk and McCoy at the trial is Michael Dorn, the actor who plays Worf in The Next Generation. The Klingon makeup is also identical, even though it is supposed to be a different character. (The makeup is actually more subdued than the makeup for TNG [flatter] but it looks similar because he is actually playing one of Lieutenant Worf's ancestors.)
Trivia: The scenes in Krone's laboratory were photographed around a real Tokamak machine, which soon afterward was disassembled & shipped to a Chinese university.

Trivia: When Kate shouts "I'm not your f*****g mommy" to Esther, this is the same final dialogue of interaction between the antagonist and protagonist as in "The Ring 2".
Trivia: At many points in the movie, the music playing in the background are slightly different versions of the song "A Hard Day's Night." This was the title track from the Beatles previous movie.
Trivia: The movie makers really wanted the audience to believe that Michael Rooker was the killer, rather than Leland Orser.

Trivia: The unit that was portrayed in the tank battle was to be the 3rd Armored Cavalry Regiment because they were actually in a friendly fire incident. During the shoot, someone showed the director the 2nd ACR's patch and he thought that was better looking.

Trivia: When Kelvin gives Rheya the pill to relax, note that she takes a sip of water first and then puts the pill in her mouth. When director, Steven Soderbergh, asked Natascha McElhone if she did this as a part of her performance, as possibly a statement that if "you are created by Solaris that is how you take a pill?" Natascha was confused and informed him that was simply how she took pills. (00:48:25)
Trivia: At one point in the movie, Kevin Bacon's wife makes a comment about him playing in 'that stupid band with your brother'. In real life, Kevin Bacon actually does play in a band with his brother, called The Bacon Brothers.
