I'm pretty sure it is Bill Condon that is attached (or rumored) to direct AIDA, not Luhrman.
I think Luhrman was more or less just making that comment, I doubt he meant that he's actually pursuing it in any way.
"Some people can thrive and bloom living life in a living room, that's perfect for some people of one hundred and five. But I at least gotta try, when I think of all the sights that I gotta see, all the places I gotta play, all the things that I gotta be at"
