I enjoyed this graphic! I think you have to read it with the methodology clear in mind but its interesting to see. This is the link in the post, which links to the three lists OP pulled from.

I went to make a profile to see how this works, and some context. As OP notes, when you make a profile, you can add up to four favorite films -- the lists are based on counting up people's favorite films. Also OP explain in a another comment the website never asks for your gender -- if you go to your profile, its default they/their -- as in "u/baydew listed Spirited Away as their favorite film" -- which is usually how websites refer to their users in automated messages. You can change this to another pronoun set in your profile if you choose to ('her', 'his', 'xe', 'ze'. also 'it' is on the list?..)

Most people probably don't touch this setting at all, but as you can see of people who do change their pronouns, those who pick 'she' do watch a different set of films from 'he'. I think its hard to interpret 'ze/xe' -- for example, I dont think its unreasonable to believe that a good chunk of 'ze/xe' are boys being silly, especially since they/their is already the default and usually the most popular choice for non-binary pronouns in most surveys by far.

Finally, I'll note that based on the lists, two movies with very large gender gaps between 'He' and 'She' are:

• "The Empire Strikes Back", skewed to men (#9 in He, not in top 100 for 'She', #23 on 'Ze/Xe')
• "Little Women", skewed towards women (#2 in She, not in to 100 for He or Ze/Xe)
