Oscar Wilde is a good choice. Very controversial because he was arrested for indecency when really he was just gay. Virginia Woolf is another good one but probably pretty popular. Also, if you can do poets, John Keats would be an interesting choice. His love affair with Fanny Brawne is documented in a movie called, "Bright Star". It's out now at many Independent theatres and coule be a unique resource for you. Of course, you'd have to make sure you do some fact checking on the movie if you decide to go that route. Good luck and have fun with it! There are so many great authors to choose from.
