Pedro Pascal’s younger sister Lux ensured all eyes were on her as she joined her famous brother at the Eddington premiere during the Cannes Film Festival on Friday night.

The actor, 50, stars in the black comedy Western as Ted Garcia, the town’s mayor who is running for reelection.

Making sure to show her support for her big brother Lux, 32, put on a dazzling display in a show-stopping gown as she stepped onto the red carpet.

The transgender activist wowed in the striking white number that clung to her svelte figure and featured a dramatically long train.

The floor length dress boasted pleats and panelling as well as a thigh-high split which exposed a little bit of leg.

Silver and gold details ran down one side, whilst the dainty straps crossed down behind her, highlighting her toned back.

Lux left her brunette locks to flow freely over her shoulders and completed her dazzling look with diamond earrings and a flawless face of makeup to accentuate her stunning features.

Pedro and Lux share a strong bond, with the Mandalorian star previously calling her one of the ‘most powerful people and personalities’ he knows. 

Speaking to Esquire last year, he gushed: ‘She is and has always been one of the most powerful people and personalities I’ve ever known. My protective side is lethal, but I need her more than she needs me.’

He added that he had always felt ‘parental’ to Lux and his younger brother Nicolás following the death of their mother, Veronica Pascal, who tragically took her own life in February 1999, when Pedro was 24 and Lux just seven.

He explained: ‘They were very young kids, so much younger than me and my older sister, so even if they hadn’t lost a parent, we would still feel parental toward them. 

‘And I didn’t naively think I could fill a space like that, but I just always wanted to be like, I’m here.’

Like her brother, Lux is also an actor, having graduated from the prestigious Julliard School in 2023, and having roles in The Prince, Invisible Heroes, and Chilean drama series Los 80.

She publicly came out as transgender in 2021, appearing on the cover of Chilean magazine, Ya, where she bravely detailed her transition.

Lux credited Pedro as being an ‘important part’ of her journey as she recalled: ‘When I officially told him about my transition through FaceTime, he asked me how I felt… because I remember that he was worried.

‘I told him, ‘I’m happy.’ And his answer was: “Perfect, this is incredible”.’

Cannes Film Festival, where filmmakers, sales agents and journalists gather from around the world, is the Olympics of the big screen, with its own golden prize, the Palme d´Or, to give out at the end. 

Filmmakers come from nearly every corner of the globe to showcase their films while dealmakers work through the night to sell finished films or packaged productions to various territories.

Over recent years the star-studded extravaganza has arguably won more attention for the outfits worn by its celebrity guests than the roster of feature films being screened on the Croisette.

The black comedy Western sees politics, conflict and unrest and is set to be released nationwide on Friday, 18 July (pictured L-R Pedro Pasca, Emma Stone and Austin Butler arriving at the premiere of the film ‘Eddington’ at the 78th international film festival, Cannes)

But new nudity rules, devised for ‘the sake of decency,’ have been implemented at this year’s festival.  

According to organisers, the austere move is an attempt to stifle the celebrity trend for ‘naked dresses’ – namely provocative outfits that reveal considerably more than they conceal – on the red carpet.

‘For decency reasons, nudity is prohibited on the red carpet, as well as any other area of the festival,’ states a Cannes festival document.

‘The festival welcoming teams will be obligated to prohibit red carpet access to anyone not respecting these rules.’ 

The surprise new policy features in a recent festival-goers charter – released with a series of outlines regarding expected public behaviour. 

Guests are expected to converge on the Grand Auditorium Louis Lumière for some of the highest profile film screenings across a packed two-week schedule in Cannes. 

It’s understood that the iconic venue now adopts a more conservative dress code, with suits, dinner jackets and floor-length evening gowns generally favoured over headline grabbing ensembles. 

Classic little black dresses, cocktail dresses, pant-suits, dressy tops and elegant sandals, ‘with or without a heel’, will also be permitted.  

While the decision to implement a more stringent policy will be a first, it is not known if French TV broadcasters, wary of airing nudity, played a role in its enforcement. 

Pedro and his younger sister Lux have a close bond and in October 2024, she joined her brother at the Gladiator II premiere at Odeon Luxe Leicester Square

Major red carpet events, including the Cannes Film Festival, are aired in France by France Télévisions

Recently attracting more models and influencers than actors and filmmakers, the annual ceremony has seen an increase in risque red carpet fashion statements. 

In 2021, American supermodel Bella Hadid bared her cleavage in a  plunging black gown while attending a screening of Tre Piani (Three Floors).

She pulled a similar stunt three years later, with guests at the 2024 gala left speechless after she attended the premiere of Donald Trump biopic The Apprentice completely braless beneath a sheer brown evening dress.
