Continuity mistake: When Tina first becomes a Buddhist, they show a scene of her chanting while Ike is in the other room turning up the volume of his stereo to tune her out. Several scenes later (and several years later, according to the subheadings) after Ike and Tina are divorced, they show the same scene of Tina chanting. Her hair and outfit are the same; it's actually the same exact scene.
Trivia: The real Ike Turner, makes a 2 second appearance just after the court sentence granting the couple's divorce. When the character of Ike Turner says, "I GAVE YOU THE NAME", the real Ike Turner is the thin man with the moustache and grey suit who follows Tina Turner's character into the lift.
