Oh, see, I was going to say Tom Ford now counts, but that's nearly going the actor-turned-director route. ;)

Jamie Babbitt! I am impressed with anyone who does TV and full-length-features because they are different skill sets and do not always translate. Also But I'm A Cheerleader has always made me happy.

Angela Robinson, similarly! Also because D.E.B.S. is, for all its over-the-top silliness, a really good movie.

I keep hearing terrific things about Julie Taymor, but I haven't seen any of her work yet.

Martha Coolidge will always have my heart for Real Genius, the first college comedy which really GOT smart people.

Kasi Lemmons directed The Caveman's Valentine, which I have not seen but my screenwriter friend continually raves about.
