The actress said it took nine months to perfect the accent alone.

During an interview with the Sunday Times, actress Ana de Armas, 32, talked about the challenges she faced while nailing her portrayal of Marilyn Monroe for the upcoming Netflix movie, Blonde. One of the biggest obstacles? Marilyn's accent.

"I tried! It only took me nine months of dialect coaching, and practicing, and some ADR sessions [re-recording dialogue after filming]," she said. "It was a big torture, so exhausting. My brain was fried."

The Cuban actress, known best for her roles in Knives Out and the upcoming James Bond movie No Time to Die (the release of which has been pushed back due to the ongoing coronavirus pandemic), also shared what it means for her to portray the iconic blonde bombshell. "I only had to audition for Marilyn once and [director Andrew Dominik] said, 'It's you,' but I had to audition for everyone else," she told Vanity Fair last year. "The producers. The money people. I always have people I needed to convince. But I knew I could do it. Playing Marilyn was groundbreaking. A Cuban playing Marilyn Monroe. I wanted it so badly. You see that famous photo of her and she is smiling in the moment, but that's just a slice of what she was really going through at the time."

Blonde is based on the 2000 novel by Joyce Carol Oates, and highlights how the Hollywood star's career took off thanks to her performances in movies like Gentlemen Prefer Blondes, The Seven Year Itch, and Some Like It Hot. Monroe, who died in 1962 at the age of 36, was also known for her stunning looks and inimitable style.

Netflix has not yet announced a release date for Blonde, but it is expected to come out sometime this year.
