. . . And you say to yourself, 'God is it ever going to happen to me.'"" The it is becoming an actress in the new catch-as-catch-can Hollywood and the me is a collective girl called Melinda Cobb (based on a number of others and their actual experiences). When first seen Melinda is moisturizing herself with a whole can of Crisco in her Sunday night going-to-bed ritual. She's also undergone a good many less pleasant things in the interests of her beauty or her art neither of which seem to matter -- it's who you know that counts. Murray is a smooth and sharp reporter and he zooms in on her as she attempts to get ahead -- a television commercial here; a course with Strasberg; an odd job as a waitress; a first audition where she's told she's ""just a typical TV nothing""; and then there are those other ways of going to bed for your job in a business where you have to be as tough as naugahyde and as resilient as polyfoam. It's an edifying and God knows entertaining vista of that not-so-best-of-everything.
