Trivia: George Clooney (Everett) was going to sing "Man of Constant Sorrow" for the film but his singing voice was very poor so he ended up lip-synching the songs instead. He said "I'm not my aunt [referring to the late singer/actress Rosemary Clooney, best known for her role in "A White Christmas" (1954)]. I decided it would be easier to just do a passionate lip-sync." He was so nervous that the tapes of his singing would get out that he returned to the studio to ensure all the evidence had been erased. The musical director of the film confirmed this but said "George is a very good singer but that style of music is very difficult and one almost has to grow up singing it in order to sing it convincingly. George did a really good version of the tune but it wasn't as good as he wanted."

Trivia: The Titans first encounter Slade while he's stealing a power crystal. They mistake him at first for the Marvel character, Deadpool and proceed to argue back and forth about him being Deadpool or not. With him saying that he's not Deadpool, that actually Deadpool should be saying he's not Slade. This is a joke and reference to the fact that the designer of Deadpool based his looks, abilities, and character originally off Slade/Deathstroke because he wanted to draw Deathstroke.
