Pop star Elton John has announced that he will be writing a new musical film about AIDS for actor and director Ben Stiller.

The singer wrote the scores for the stage adaption of Billy Elliot in 2005, and Broadway version of The Lion King, and is now branching out into more controversial material.

John told GQMen.Style that the musical is “about a guy on Broadway who is gay, has HIV and AIDS, and has to go back and face his wife and kids that he left.

“It’s very funny. The premise doesn’t sound funny, but it is. Alright?”

When asked about his attitude towards musicals generally, John said that he was not usually a fan of the genre. He said:

“I like some of the classic ones.

“‘West Side Story,’ for me, is the greatest musical ever written. But I don’t like forced fun.

“I’m more drawn to tragedy than ‘Let’s all have a great time,’ and I’m not keen on the music in musicals sometimes.

“I’m quite fussy about it. I don’t really like them unless I’m involved in them, for some reason.”
