Responding to the backlash Ana, who only learned English in 2015, admitted that she ‘didn’t grow up knowing Marilyn or her movies’.
‘I am proud to have Andrew’s trust and the chance to pull it off. I feel like whether you’re a Cuban or an American actress, anyone should feel the pressure.’
‘My job wasn’t to imitate her,’ defended Ana, who spent nine months working with dialect coach Jessica Drake.

‘I was interested in her feelings, her journey, her insecurities, and her voice, in the sense that she didn’t really have one.’
While Blonde is not fully-authorised by the Marilyn Monroe Estate, Ana’s performance has had plenty of early plaudits.
The rep for Monroe’s estate Marc Rosen told Variety on August 1: ‘Ana was a great casting choice as she captures Marilyn’s glamour, humanity, and vulnerability.’
The casting was also defended by two-time Oscar winner Brad Pitt, who’s one of Blonde’s six credited producers.

‘She is phenomenal in it. That’s a tough dress to fill,’ the Plan B Entertainment co-founder told ET on August 1.
‘It was 10 years in the making. It wasn’t until we found Ana that we could get it across the finish line.’
Blonde author Joyce Carol Oates and Jamie Lee Curtis – whose father Tony Curtis (played by Michael Masini) co-starred with Monroe in Some Like It Hot – have both seen the film and fully approve.
