It's a bit hard to think of any other dead gay character barring royalty who has had so many movies made about him as Oscar Wilde. The latest - and according to reviews - arguably the best is "The Happy Prince". Although it was premiered at the Sundance Festival last October, I have not seen it listed in Bangkok so far. It was written, directed and stars the gay Rupert Everett whom The Guardian describes thus in it review -
"It is a part he was born to play., and he does it with exactly the right kind of poignantly ruined magnificence."
Unlike other Wilde movies which start before the scandals, this one begins in Naples and Paris where he sought refuge after being vilified as a result of his prison sentence in England. I wonder if any readers have seen it.
