Hollywood actress Margot Robbie has spoken about her experience playing the role of a wild child star of silent cinema in her latest film, Babylon.

Speaking at the London premiere of the film, Robbie said that she found the experience “liberating.”

The film is directed by Oscar-winning filmmaker Damien Chazelle, who has taken inspiration from the outrageous excess and rampant debauchery that supposedly went on behind the scenes in Hollywood in the 1920s.

As Nellie LaRoy, the character that Robbie plays, filmgoers will see her consume copious amounts of drugs, cry with great precision on cue for the camera, and even wrestling a snake while drunk.

Speaking about the experience, Robbie said “I was allowed to do absolutely anything and it was just so liberating… it was just madness every day on set.”

Robbie also spoke about the difference in moviemaking during the 1920s, saying “It was a different ball game. I would loved to have seen moviemaking back then, it seemed like there were no rules and it was just madness.”

When asked about the drunken kiss between her character and Brad Pitt’s character, which was entirely improvised, Robbie said that pretty much all of the chaos that unfolds onscreen was already down on paper.

“It was of the best dialogue I had ever read, and the best sequences, truly – you could improvise for fun but the script was so stunning.”

Robbie was nominated for a Golden Globe for best actress in a musical or comedy, but lost out to Everything Everywhere All At Once star Michelle Yeoh.

Additionally, Babylon received nominations in several categories including best film (musical or comedy), best actor for Diego Calva, best supporting actor for Brad Pitt, and in best original score.

Composer Justin Hurwitz, who won an Oscar for his La La Land score, took home the film’s only Golden Globe.

Other big winners on Tuesday night included Steven Spielberg for his personal drama The Fablemans, which won best drama, plus Colin Farrell for Irish black comedy The Banshees of Inisherin.
