Thank you for this analysis. It is an interesting piece, but has a few problems, for example not looking at whether more lines would be appropriate to the character. Taking Deadpool as an example, Negasonic Teenage Warhead is a sulky teenager. Giving her more lines would break the character.
What would be more insightful but very difficult to do would be the comparison between the number of roles spoken in similar roles by male and female characters. Do female leads have the same number of lines as male leads in similar films in the same genre? AngelDust for example is a badguy bruiser in Deadpool, but has only one line. Do similar male characters in such supporting roles in other superhero movies get more lines, or the same number? Does Dory have more or fewer words than Nemo?
The issue of their being fewer female characters in these roles is another thing to challenge.
