Jessie Buckley and Penelope Cruz Shine at Premiere!

delighted fans as she signed autographs before heading into the afterparty following the UK premiere of her new film The Bride! on Thursday.

The Irish actress, 36, was joined by her glamorous co-star , 51, who stunned in a black sequinned gown with a red clutch bag.  

The Hollywood star displayed her ageless appearance as she made her way into the star-studded bash, which was held at Bardo St James's.

Jessie and Penelope was joined by the likes of host and .

The director of the anticipated movie, 48, was joined by her actor brother .

Jake made a rare public appearance with his long-time girlfriend Jeanne Cadieu, who wowed in an optical illusion dress.

She may be well on the road to an Oscar next month, but it was back to work for Jessie as she attended the premiere of her newest film The Bride!

Jessie is worlds away from her acclaimed role in Hamnet as she stars as a woman resurrected as a spooky companion for Frankenstein's monster.

Arriving on the white carpet at Cineworld Leicester Square, Jessie channelled her on-screen heroine in a daring sheer gown.

The revealing look flashed a glimpse of her underwear as she posed for a string of playful snaps at the launch. 

Christian Bale, who stars as Frankenstein's monster in the film, was supported by his wife of 25 years Sibi Blažić.

The British actor is no stranger to transforming himself for roles, as The Bride! was no different, as he previously revealed that it was his transformation for his latest role that proved to be the most challenging - despite it requiring no effort from him at all.

In order to get into character, Christian would have to spend six hours every day in makeup, with sitting still for such a long period nearly turning him 'insane'. 

He found being inactive such a struggle that he would have to 'scream like crazy, every day' on set, explaining: 'Just to [release the] despair, all of that restraint that you have to display when you're sitting still for that long.... 

'I didn't want to do it driving into work because I thought I might cause a crash. And I didn't want to do it by myself because I thought everyone would just think I'm going nuts.'

Christian added to Entertainment Weekly that he enlisted his hair and makeup team to unleash a primal scream with him every day, which he says was a 'great bonding experience'. 

He continued: 'Oh man, I'm telling you, the whole crew got involved by the end, because people would hear us screaming.

'We would open the doors, and gradually, a bit like the Bride's revolution, a few people were going, "Can we do it too?" And then by the end, there were like 30 people who would hear us and run to the makeup trailer to be a part of it and scream.'

While the lengthy makeup sessions would no doubt prove taxing for many, it's interesting that Christian found them such a struggle given his history with pushing himself to the limits for his film roles. 

Despite insisting he is not a method actor, Christian has adopted dangerous methods to get into character, most notably losing 62lbs in four months in order to play an insomniac factory worker in The Machinist. 

The Bride! takes place in 1930s Chicago when Frankenstein's monster asks Dr. Euphronious to create a companion for him.

They give life to a murdered woman known as 'the Bride' which sparks romance and police interest. Peter portrays a character named Jake Wiles in the film. 

Jessie won the gong for Best Actress at the BAFTA awards on Sunday night for her role as Agnes in Hamnet.

Reflecting on her role, the Irish actress admitted it has made her 'braver in her life'.

Praising her director, she told W magazine: 'Chloé is such an artist in that she's looking for people's somatic responses to the material. She's always trying to distill it to the most primal vibration between us all.

'Where Agnes had to go, and how brave she was to sit in something that is unfathomable and let it rip through…I think it has made me braver in my life.'

On Sunday the star fought back tears as she dedicated her BAFTA win to her baby daughter whilst making history as the first Irish actress to receive the award.

As Jessie's voice became shaky with emotion, she said: 'I'd like to share this with my daughter who has been with me since she was six weeks old on the road with this.

'It's the best role of my life being your mom and I promise to continue to be disobedient so you can belong to a world where all your mad, complex wildness as a young woman.'

She concluded before the room erupted into applause: 'I am very grateful for this, thank you so much.'

Jessie welcomed her six-month old daughter with film producer husband Freddie Sorensen last year and has yet to reveal her name.

Jessie was nominated for the prestigious award alongside Renate Reinsve for Sentimental Value, Rose Byrne for If I Had Legs I'd Kick You, Kate Hudson for Song Sung Blue, Chase Infiniti for One Battle After Another and Emma Stone for Bugonia.
