Salma Hayek has admitted that she was worried about playing herself in the new season of Black Mirror.The actress appears in the sixth season of Charlie Brooker’s dystopian anthology series, starring in an episode titled ‘Joan Is Awful’.In the episode, a woman named Joan (Annie Murphy) learns that her life has been turned into a TV show on a Netflix-style streaming service, with Salma Hayek playing her.Speaking to Radio Times about her role, Hayek said that Black Mirror had gifted her “a once-in-a-lifetime opportunity to play an interpretation of myself”.“I got to explore the concepts and clichés people have about me and be self-deprecating,” she said.“It’s as if I created an alter ego where I could do the most disgusting, grotesque things that you would never do in real life… and have permission to do that.”Hayek added: “There are so many moments that shocked me in the script. There is one huge one that I had to come to terms with, and made me ask myself, ‘Do I really want to do this? Am I going to get in trouble?’’”‘Joan Is Awful’ co-stars Michael Cera, Ben Barnes and Rob Delaney.
