Mick Riva isn't just one of Evelyn's ex-husbands — he's also the dad of the gang in "Malibu Rising," another of Jenkins Reid's novels that's being adapted. Fans on social media have been clamouring for Harry Styles to play the fictional Mick, who is also a music superstar. Styles added two films to his acting CV in 2022 — "Don't Worry Darling" and "My Policeman" — and while his performances didn't get rave reviews, he could shine in "The Seven Husbands of Evelyn Hugo" as a character who's a little closer to his real personality.
