Gina Carano's voice was dubbed over with actress Laura San Giacomo's voice.
Knowing this really stops me enjoying rewatching this. It is kind of jarring. Anyone know why this was done? I don't hear anything wrong with Gina's voice in other films.
From what I understand her voice was altered but it was not dubbed.
"Steven Soderbergh wanted Mallory and Gina to be two completely different entities. I think in the sports world you end up falling in love with the person that is Gina Carano, and it makes it a little bit more difficult to take me and put me into a Mallory Kane type of character. And so he did do some altering and mixing... and we went back into ADR and he worked really hard at making Mallory be a different entity. And he did a really genius job in that. It's just an honor to be part of it, whether there's altering or not. THere's a little joke I was saying: even if he would have shaved my head and put Bill Clinton as my voice I would have still done it."
