In Hollywood, are there more main roles for male actors than female (actresses)?
Are there generally more roles for male actors than female (not just leading ones)?
It probably depends on the genre. I use to search for action, thriller, crime genres, but I believe it happens not only in these ones.
For instance, in "Bollywood" there may be very different stats.
I just have this feeling when I scroll down IMDB lists, and most of the times the leading roles are on male actors. And when I find a female leading role, I'm used to see many male actors behind. Maybe that just happens in my preferred genres. Or maybe it's just a general fact. I don't know.
I've also read female leading roles in action movies don't use to do so well in box office, and maybe that affects the listings order. I would like to check that too, and see if there's any evolution or not.
Besides a confirmation on such assumption (I don't know if it's true, because I don't have stats) and any reason on why (too broad for a question), I would like to know stats.
Is there any website with statistics on male versus female presence in movies and/or leading roles?
