Kidman, 54, who received her fifth overall Academy Award nomination for her performance as Lucille Ball in Being the Ricardos, missed the event at the Fairmont Century Plaza Hotel in Los Angeles because she's back home in Nashville recovering from a torn hamstring — and old injury that flared up while she was filming Amazon Prime Video's upcoming drama series Expats this week — Variety reports. A source confirms to PEOPLE that the award-winning actress is okay and is just taking it easy as she recovers, per doctor's orders.

Axelle/Bauer-Griffin/FilmMagic While speaking with PEOPLE about the biopic, which explores the dramatic professional and personal lives of Ball and Desi Arnaz, the film's costume designer, Susan Lyall, opened up about the intense process of recreating the on-screen looks for the characters. Aaron Sorkin Defends Casting Nicole Kidman as Lucille Ball: 'She's Not at All Lucy Ricardo' "I might have watched the Fred and Ethel Fight episode, in its entirety, maybe 15 times and then kept freezing frame and moving in closer and trying to suss out every detail of the costume, and the same with Lucy," said Lyall. "I watched the grape stomping [scene] over and over and over again, to get every detail correct in order to recreate it exactly."

In November last year, Sorkin, who wrote and directed the film, defended his decision to cast both Kidman and Bardem, 53, in an interview with The Hollywood Reporter. "We made this movie during COVID, and so in Zooming with Nicole and Javier and everyone else, I'd make it very clear to them that I am not looking for a physical or vocal impersonation of these people," he said. Sorkin also explained how the movie shows a broader portrayal of Ball and Arnaz's life together, with "less than three minutes" of screen time showing Kidman as Ball performing on the sitcom I Love Lucy. "So, finding an actress who looked like Lucille Ball wasn't important to me, especially because I was excited by the idea that Lucille Ball doesn't look like Lucille Ball — and that every time we're seeing Lucille Ball not as Lucy Ricardo, she should both literally and metaphorically let her hair down," he explained. "Let her be what she's not allowed to be on TV in 1952 on CBS. Let her be a woman. Let her be sexy. You weren't allowed to be sexy on TV."
