I do, but it’s not a point worth mentioning, honestly it’s not.
You want the same face throughout so as not to confuse people. It happened in the 90s, not everyone knows what Harding really looked like.
Showing real footage at the end just puts the reality next to the portrayed, it’s different, not the same thing at all. The real Tina Turner turns up in the biopic about her right at the end to. It reinforces that they’re real people, that this story really happened.
