Transsexual
Hmmmmm ... If I could produce and direct a TS movie, it would be with the the following TS women:
Lilliene Lee would be my first choice, but I read somewhere in here where she has basically retired to academia.
Sapphire, who was on "Transsexual Beauty Queens #1" I believe, would be on it also. What a cutie!
Barbie -- that ubiquitous voluptuous blonde -- would be on there in a heartbeat. What a dream!
Madison -- Yum-yum! What a face. 
And, if I could get only one from Brazil, it would certainly include Camilla de Castro, although there are tons of beautiful women down there to pick from. Dozens.
From the Eros sites ( going strictly on their ad pictures ) :
Hmmmmm, yes Siagon Lee and Seren Love would certainly be in, as would Stephanie Cummings and Nikki. Claudia and Venus from the New York Eros site would be in it, as would Sophia, Lesly, Mila and Savannah from the SF bay area... There are too many to list now that I think of it. Too many.
FWIW ... I know one has only so much tape and time, and it depends also on what kind of movie one is striving for, but I would display more of their femininity if possible, as well as displaying more of their womanly figures in the buff whenever possible. Whatever became of basic erotica -- You know, working on what's between the viewer's ears ?!
If such a movie has a premise, and mine would try, I would show them showering, painting their nails, trying on a new wardrobe barefooted in front of a mirrored wall, or simply show them near the window sill flexing her legs ( I can just picture Lilliene having this role ) awaiting her lover while immersed in some reverie.
The crude close-ups of simply showing intercourse gets old mighty fast imho. Getting from point A to point B should be an erotic journey of some sort, not wham, bam, thank you, mam.
Well, those are my two cents.
"P"
make some of these girls wear pantyhose,,, a t-girl in pantyhose is so erotic,,, and also how about a strictly oral line,, such as the "bj adventures of dr fellatio" from evil angel,,, an all oral t-girl movie would be a killer,, have them preform on guys and other "gals"
just a thought from a t-girl,oral,pantyhose lover,,,
