The question is a bit confusing...but I'll reword it the way I understand it.
"If you had a choice to replace one character in a movie already made, what movie would it be and who would the character be?"
I'd replace that skank with the horrid accent Penelope Cruz as Mirtha Jung in Blow. I'd be a great , supportive wife to George, and I'd influence him sweetly not to mess things up with Diego and just be an awesome mother, wife, partner and lover. (I can dream, cant I?)
If you had to party for a week in a hotel with two celebrities, who would they be and why?
