Define crush? There are lots of actresses I find physically attractive or have over the years. (I remember having a crush on Shirley Temple when I was under 5) I was at a family dinner in the last couple of years and I found an actress ahemable when I suddenly felt really old as another actress, playing her mother is one that I had a thing for, for years (type I am attracted to): Katharine McPhee and Lea Thompson. There is one I have always been attracted to and as a kid would have loved to meet, and that is Linda Hamilton. The gal I proposed to at first reminded me of her, now LH reminds me of the gal I proposed to and given how small I know the world to be (I can play the Keven Bacon game two different ways/less then five degrees), I wouldn't want to meet and spoil the fantasy.
(happened before where a friend went to introduce me to another friend of his and I still can't watch his show. It would be to me, the same as watching a parent/relative act, not going to see the character)
