In the film, Ike is the father of Tina's first child, Craig. In real life, Tina dated Raymond Hill, saxophone player for the Kings of Rhythm, before she met Ike. Hill was Craig's biological father; Ike adopted Craig when he and Tina got married. The movie also portrays Ike Jr. and Michael as the oldest of the four boys. In real life, Craig was the oldest, followed by Ike Jr. and Michael (Ike's children with Lorraine Taylor), then Ronnie Turner, Ike and Tina's only biological child.
Vanessa Bell Calloway, who plays Jackie, the friend and former Ikette who shares Buddhism with Tina, was wary of chanting the Buddhist words because of her strong Christian faith. Director Brian Gibson allowed her to mouth the words silently during taping, and added the words with a voice double in post-production.
Angela Bassett was injured while filming the first spousal abuse sequence. She fell off the back of a high-rise sofa, put her hands out to reduce the impact, and suffered a hairline fracture of her right hand. She only tried the stunt fall once, and footage leading up to the mishap appears in the film.
Jenifer Lewis, who plays Tina's mother in this film, originally auditioned to play Tina Turner. Lewis is only two years older than Angela Bassett, who plays Tina. Interestingly, when Ike first comes to the Bullock household, he asks Lewis to speak to Tina's mother as though the two women were sisters, which is closer to reality than film continuity.
The scenes depicting Dallas, Texas were based on Tina Turner's real-life domestic violence fight where Ike Turner and Tina were scheduled to perform at the Dallas Statler Hilton in July 1976. This was depicted in Tina's autobiography in graphic detail (including her walking to the Ramada Inn Plaza Hotel across the way) - the reference to her having 36 cents and a Mobil credit card was real. The Statler Hilton was sold in early 2011 to a real estate developer who intends to restore the hotel to its original state as it first appeared in 1956.
In Ike Turner's autobiography "Taking Back My Name", he said that the scene where he beats and rapes Tina in their home studio, and the scene where he confronts her backstage with a handgun, never happened.
