Back in 1997 or 1998 (memory's a fickle friend), Australian choreographer John O'Connell had dinner at director Baz Luhrmann's Sydney home, alongside Luhrmann's co-writer Craig Pearce and producer and costumer designer (and also Luhrmann's wife) Catherine Martin. "We sat around the dinner party and he just had an idea," O'Connell tells EW. "No script, nothing. But he's very persuasive. We had a great dinner party and I walked out and said, 'I think I'm doing another movie.'"
