LOL "I'm a dude playin a dude disguised as another dude."

Yep, Anne Coulter.

Actually, women do have an adam's apple- I looked it up- it's just smaller and less noticeable than a man's. I've noticed many women with them.

Like a previous poster wrote check for an Adams apple, and sure enough Gwendolines got one. Change evreything you can that is the one thing they can't.

Gwendoline is played by Anne Carlisle. She is definitely female - she has acted in several roles, all female.

Fran is also played by a female actress. Her name is Anne Francine. She had all-female roles her entire career. (RIP) http://www.imdb.com/board/20290022/
But I have to agree with the OP: Why did they hire a woman to play a man playing a woman?

In which scene? In the scene where Mick meets Gwendoline, I could have gone either way on whether or not that was a man in drag. She looked very feminine at times, but also had a few somewhat masculine features. Turns out, Gwendoline was played by a woman. Later, at the party scene where Mick grabs Fran's crotch to make sure Fran is a man/woman, Fran is played by a female, though I would've sworn to you prior to looking at the credits that the character was played by a male. And after having viewed that scene between Mick and Fran,
I'm still not sure what Mick found when grabbing Fran's crotch? Was Fran actually a man or a woman?
Fran was a woman, hana

I had Gwendoline pegged as a man immediately.

This signature has been deleted by the poster

Its the opposite to Life of Brian where they had men playing women pretending to be men

Looked like a man just before Mick grabbed the crotch. But the voice was definitely a woman's. Anyway, if he wanted to tell if it was a man, he could have just looked for an Adam's apple.

Her voice was very feminine, not manly at all,
lol u must have not met many dross dressers. I've seen some before and some are pretty convincing, esp in the voice.

I guess I'm going to have to be one of those people that disagree with you- I think his/her features are very feminine, and so is her voice. Does anyone know anything about this actor/actress? Her name is Anne Carlisle and she has a few credits on IMDB- Miami Vice, etc.

Based on the facial features of "Gwendolyn" you can pretty much guarantee that its a man. Some people have said "but she was actually a girl." I'm not buying that.
People who say this are probably going by the name of the actor in the closing credits to assert that the character was actually a women, yet that can still be off base as the person could be a hardcore transvestite, and obviously preferred to be named by her woman name, not her birth man name..who then plays a man dressing as a women

The scene I was referring to was the one with Gwendolyn. To me, it was pretty clear she really was a she, not a man. I felt they just should have had a man play that part. Her voice was very feminine, not manly at all, but then when Mick grabs "her" crotch, they dubbed in a man going "Oh!" (I'm pretty sure they did, that's what it sounded like!) I'm just not sure why they did that. As far as Fran, I'm pretty sure Fran was a woman, although I too would've swore she was played by a man! (I have to wonder as well what Sue was doing at a party with coke-sniffers, prostitutes, etc!)
