This is an almost tautological position though. Films have a gender bias because society has a gender bias because, among other things, films have a gender bias. The reality is human beings have agency to make new things, dismantle previous stereotypes, and create an equal footing. Female action stars are not a concept that puts us at an impasse for creating gender equality (in fact, I'd argue with things like the Hunger Games, some of the marvel films, etc. the trend is to begin featuring women incrementally more in action films). I still haven't seen any evidence that gender stereotypes or prevalence of women are a causal factor in profitability, but even if that were the case I think we need to ask ourselves if that's a just position to take for defensibility.

I haven't seen any evidence that gender equality in film dialog is a good thing.
