Personally I was hoping that Great Directors would make it too, but I guess the Great Writers category encompasses theater/film too. As for the ones I would like...
Great Musicians:
*John Lennon/The Beetles (Prediction, rather than a hope)
*Madonna
*Frank Sinatra
*Johnny Cash: I Walk the Line/Ring of Fire
*Andrew Lloyd Webber: The Phantom of the Opera
*Michael Jackson: Thriller
*Richard Rodgers/Oscar Hammerstein: The Sound of Music
Great Writers:
*Aldous Huxley: Brave New World (Duhh)
*Alferd Hitchcock: Vertigo/Psycho
*Ayn Rand: Atlas Shrugged
*Joephy Conrad: Heart of Darkness
*George Orwell: Nineteen Eighty-Four
*Mary Shelly: Frankenstein
*Orson Welles: Citizen Kane
*Sydney Howard/Victor Flemming: Gone With the Wind
*Stanley Kubrick/Arthur C. Clarke: 2001 a Space Odyssey
Great Painters
*Emanuel Leutze: Washington Crossing the Delaware
*Jacques-Louis David: Napoleon Crossing the Alps (I like crossings, okay?)
*Vincenzo Camuccini: The Death of Ceaser
*Eugene Delacroix: Liberty Leading the People
Then again I'll probably have to mod most of these in myself... And learn how to do that in the first place.
