It’s made up of Absinthe and, erm... the tango?
Speaking to Variety recently, the pair reflected on the ‘absinthe-filled party’ that was the making of Moulin Rouge.
“We’d have great parties! Remember those Friday nights?” asked Kidman.
“Not all of them. Don’t remember all of them,” quipped McGregor.
“We had some pretty wild nights. I remember absinthe being passed out at one point, and me going ‘Is this safe?’ I was so naive,” said Kidman.
“Then going, ‘I suppose it is!’ Dancing on the tables...”
When Kidman and McGregor weren't dancing on the tables, they were learning how to tango and salsa, and spending hours in workshops - and that's how they formed their intense bond.
“All those workshops we did — we’d work on a scene, then a week later the work we’d have done would be incorporated into the writing. That almost never happens,” said McGregor.
“When you work together like that, what you created is yours forever. It bonds you together in a very particular way,” said Kidman.
“We gave about a year of our lives to that film, but hey, I’m so glad.”
The film, which was produced by Baz Luhrmann, was filmed in Sydney over 1999 and 2000.
