I utilize plot and dialogue in most of the scenes which I write and direct, and I can't tell you how frustrating it is to work with adult industry performers that only want to fuck...
Over the years I have developed techniques for getting good performances from people who have insisted that they could not act. They were in fact surprised at their own performances afterwards.
When I get the opportunity to work with performers who actually enjoy the acting part, it is a true joy, and it shows in the finished project.
My "A" list of Asian adult actresses includes Evelyn Lin, Lucy Thai, Annie Cruz, Mika Tan, Charmane Star, Nautica Thorn, Keeani Lei, Kaiya Lynn, Tia Tanaka, and Lana Croft, all of whom I have worked with multiple times. I only worked with Asa Akira and Mimi Miyagi each once, however they were both great to work with.
Among the best male performers I have worked with are Dale DaBone, Nick Manning, Otto Bauer, Marcus London, Alan Stafford, Eric Swiss, Hershel Savage, Steven St Croix, and Alec Knight. I have not worked with Barrett Blade yet, but I was on another director's set watching him act once, and I was really impressed with his acting ability.
There are many amateurs whom I have worked with that gave some good acting performances too, but I doubt anyone would recognize their names.
Now when it comes to adult "performing", that is a whole other category...
