Also, both the book and the film of The Celluloid Closet are awesome. I was privileged to see Russo speak shortly after the revised edition of the book came out.

I have since seen (and read) it! I recommend Richard Barrios' Screened Out: Playing Gay in Hollywood from Edison to Stonewall (2003), too, if you haven't read it. But I never heard Russo speak, and I'm glad you did.
