Pedro Pascal and His Sister Lux Bring Family Support to the Premiere of ‘Behemoth!’

Pedro and Lux Pascal are one of the most iconic sibling power duos. The two arrived on the red carpet at the BFI London Film Festival in subtly coordinated outfits for the premiere of Behemoth!

Despite their stunning ensembles, their most important accessory was their obvious connection, shown through affectionate hugs, smiles, knowing glances, and mutual support. These photos, fit for a family album, are a breath of fresh air, given that showbiz is filled with family feuds and heated rivalries.

Behemoth! follows Alex Serian, played by Pedro. Alex is a highly skilled cellist who returns to the city where he grew up after 20 years away from Los Angeles. He comes from a family of musicians with close ties to Hollywood, and as a child, he was a prodigy. His parents encouraged him to pursue music, sharing the same passion, although their relationship to the art form was fraught. Despite Alex’s talent and the possibility of a prestigious career, he has spent much of his life distancing himself from that world, which expected too much of him.

His return to Los Angeles is yet another form of escape, this time from a burgeoning career in Chicago and a romantic relationship with a woman named Carol (Olivia Wilde). Now, Alex wants to be close to his ailing mother and mend his relationship with his brother, played by Will Arnett. Meanwhile, Alex returns to playing in orchestras that score movies, finding himself immersed again in the musical world he tried to leave behind.

Taking on this role wasn't easy for Pascal. During the event at The Royal Festival Hall, the actor described how challenging it was to play a cellist, especially given the need to play the instrument convincingly: “I’d never been so afraid,” he said. “I’ve ⁠been nervous about other jobs and the physical...emotional demands, but it was nothing ​like this,” he confessed. “I would choose fighting The Mountain in Game ​of Thrones over learning how to play the cello convincingly. I would rather be, I don’t know, tossed off of a cliff with Nicolas Cage than have to learn how to ​play the cello.”

Despite his initial fears, Pascal fully committed to the role, saying he took his cello with him practically everywhere—even to the gym and while running errands. He said learning to play the instrument was a bit like starting a relationship: a challenge at first, then an increasingly comfortable bond. “Once I held the cello, I ‌felt ⁠good.”

Seeing Lux by Pedro’s side is nothing new. His sister stole the show at the 2024 premiere of Gladiator II. His older sister, Javiera, accompanied Pedro to the 2025 premiere of Fantastic Four.

Pedro fully reciprocates his sister Lux’s support, cheering on her projects in both film and fashion. Furthermore, when Lux came out as a transgender woman, Pedro wore a T-shirt bearing the slogan “Protect the Dolls,” a statement of solidarity with the trans community.

At the premiere of Behemoth!, the actor didn’t miss the chance to make this known. When he spotted a fan in the audience wearing one of the famous T-shirts, Pedro shouted out, “Protect the dolls, always and forever!”

Behemoth! will hit theaters on December 4. We’re betting Lux will be in the front row, ready to cheer on her brother once again.
