WEST HOLLYWOOD, CALIF. — Margot Robbie came racing into the tucked-away bungalow she was renting here. She had returned from recording the voice of a talking dingo for a DreamWorks animated movie, and on an April afternoon was doing her best to clean up strewn clothes from overstuffed suitcases — evidence that an intended one-week visit to Los Angeles had stretched into a month.

“I’m sorry it’s so manic,” said this 25-year-old actress, who was born in Gold Coast, Australia, and lives in London, yet had not seen either city in a very long time.

“I’m always like, ‘No, it will calm down next week,’” she said in a more relaxed moment, stretched across a patio couch next to a faded pillow that said “God Save the Queen.”

“And then the following week ends up being crazier.”

Ms. Robbie was on the latest leg of the globe-trotting journey that has consumed her since 2013. It began at roughly the moment that a worldwide audience discovered her in Martin Scorsese’s “The Wolf of Wall Street,” playing the no-nonsense lover-turned-wife of an unscrupulous broker played by Leonardo DiCaprio.
