Character mistake: In the scene before the New Haven concert, when Jim is talking with the reporter/ love interest about his school history, she comments that Jim attended the University of Florida. In actuality, Jim attended Florida State University.
Character mistake: When Dolph is looking at the logo for the Red Dragon brewery, he says, "That arrogant scumbag mother fucker. He put the yakuza iron claw right on the logo." But, the iron claw is not the logo of the yakuza. It's the logo of the specific syndicate run by some members of the yakuza, as Dolph stated after ripping open the shirt of that guy in the interrogation room. So, he just wrongly stated what the logo really belonged to.
