Although the title would suggest that all Latin girls love in the "backdoor", apparently only one actress is in this movie. Props go out to Justine Romee, who must've had the easiest audition in the world. That is, if you can fully classify hardcore buttsex as an "audition".
Now, perhaps it's because I'm growing ever older, and hopefully wiser, but Justine Romee doesn't sound like a Spanish name to me. So, as I've mentioned, you'll excuse me if I have doubts about validity of the claim of this movie. I certainly don't ever recall Rita Moreno ever talking about her wild anal adventures.
So, I must exclaim to the director, Lee G. : "Caput tuum in ano est!"
