Margot Robbie can't understand why 'Babylon' didn't do well at the box office.

The 34-year-old actress starred as Nellie LaRoy alongside Brad Pitt in the comedy drama film - which was released in 2022 - and Margot still can't understand why it wasn't a big hit with cinemagoers.

During an appearance on the 'Talking Pictures' podcast, Margot shared: "I am still saying [why didn't it prove popular]. I love it."

Margot ultimately hopes that the movie will develop cult-classic status.

She said: "I know I am biased because I am very close to the project and I obviously believe in it, but I still can't figure out why people hated it.

"I wonder if in 20 years people are going to be like, 'Wait, 'Babylon' didn't do well at the time?' Like when you hear that 'Shawshank Redemption' was a failure at the time and you're like, 'How is that possible?'"

Meanwhile, Margot is currently "enjoying" the challenges of motherhood

The movie star and her husband Tom Ackerley recently welcomed their first child - a baby boy whose name and birth date have yet to be revealed - and the loved-up couple are relishing the challenges of parenthood.

A source recently told PEOPLE: "They have been hanging out in [Los Angeles] as a family. Tom's mom has been visiting from England."

Margot plans to return to work in 2025 - but, for the time being, the actress is keen to spend some quality time with her baby boy and her husband.

The insider shared: "Margot has several projects lined up next year. She wants to rest now and spend time with the baby. She's enjoying motherhood."
