Thinking in 'lala-land', i would LOVE to be in a zoo-movie! We all (or at least most of us) like to see the action, and the idea of others watching me get ravaged on screen - preferably in de best quality - is in itself an enormous turn-on!
Not thinking about payment yet (which i would still go for; as the 'dark-knight-Joker' said: "If you're good at something, never do it for free"), i would get an enormous rush of reading comments of viewers, seeing how they liked it, what they liked the most, or even taking their suggestions for the next video. And no worries of course if my face would be on it or not. Heck, it probably should be, so show my reactions, or if i wanted to say thank you to the viewers or smiling kiss & wave goodbye when the video is done... ?

Owk, now back to reality... HECK NO, 'caus for one; i'd go to jail in my country! ?
Second, as with any porn on the internet, it'll spread like Corona... (without the facemasks and social distancing that is, you get what i mean).
Even when adding full facemasks or framing faces off-screen, there'd still be plenty of pointers to find out who was in the footage, and where it was recorded: they'll recognise pieces of clothing, colors of walls, or listen to their languages and even accents.
And even if it weren't for the legal penalty's, the social shame would be to great of a risk.
The only realistic reason i would do such a film, would be out of desperation for the money... which would have nothing to do with zoo or sexual interests.
Owk, maybe some day, ages from now, i could hypothetically release my old footage from when i was younger, when i'm totally not recognizable anymore, - by which point HD and 4K resolutions are probably hopelessly outdated - to reminisce on old times.
But that would be my only conceivable, realistic way... and would be decades off...
