“Emilia Perez”, a musical crime comedy film about a Mexican drug lord who wants out of the cartel and undergoes a sex change, premiered at Cannes on Saturday. The film – directed by French master Jacques Audiard – has received glittering reviews, suggesting it may be in line to win the top prize the Palme d’Or. Popstar-turned-actor Selena Gomez stars as the boss’s unsuspecting wife in a surprisingly gritty role. During the film’s press conference, she answered a journalist’s question about how her character could mark the history of cinema.
