Usually scrawnier and skinnier girls make for easier animations, and as movies compete, they cast roles for them, too.
since the heroines are scrawny and cool they want to be scrawny to be cool.
If you are referring specifically to scrawny action heroines, then they look like they don't work out because they don't.However, if you're referring to modern heroines in general, then your question is not true for all modern heroines. Look at Halle Barry in Catwoman, Milla Jovovic on Resident Evil, etc. Those women are in great physical shape, and although they are thin, you can tell they do work out.
they do it to make people think they'll look like that.
There are no movies like this.
The movies are live action, but some of the magical creatures are computer animated.
First of all, none of those women are scrawny, look at Wonder Woman, she was skinny and well-shaped sure but she was far from scrawny. And skinny women do not lack power or strength, some of the most powerful women I know are extremely skinny. Don't stereotype, it doesn't make anyone happy.
I dont think it has to do with their body size, instead their gender. Women are bitches. No man, hero or villian wants to hear the excessive nagging of the female
Skinny does not mean scrawny. The women who play those roles are muscled, but lean. They are just as fit to play those roles as anyone. And just because someone is skinny does NOT mean they are weak. That's like saying someone can't run because they are fat. Theses stereotypes are not worth perpetuating.
A live action movie is shot using real actors and sets instead of animation and/or computer graphics. Live action movies can contain some elements of CGI and animation
Fox Action Movies was created in 2012.
Most recent film was ( Flintstones) live action, not cartoon, the Modern stone age family.
Because that's what most teen boys are attracted to.
