Sydney Sweeney details extreme role preparation ahead of The White Lotus

Emerging US actress Sydney Sweeney has detailed her unique groundwork for acting roles, and her latest gig on The White Lotus was no exception.

She may only be 23 years old but US actress Sydney Sweeney is a seasoned professional when it comes to her roles.

The up-and-coming Euphoria star is among the glittering A-list cast in HBO’s miniseries The White Lotus, which premiered its debut episode on Foxtel on Monday.

She told news.com.au about her extreme preparation with creating comprehensive backstories for the roles she plays, including for her The White Lotus character Olivia Mossbacher, the daughter of a wealthy CFO.

“I create these ginormous journal book concept things and I start from literally the day she’s born and build an entire timeline of her life up until the first page of the script,” Sweeney said.

“So describing her backstory would be a whole week process,” she added.

“I literally know what her daycare was when she was five, and what was inside her locker in middle school, versus what she has in high school.

“So, she definitely had a different privilege than other characters. She didn’t ride a bus, her parents always drove her places, different little things like that.

“A full backstory (would be) a long talk.”
