She plays a chaste missionary in Murder On The Orient Express.
But Penelope Cruz showed off her racy side as she attended the film's world premiere in London on Thursday clad in a dazzling sequined gown.
The Spanish actress, 43, oozed sex appeal in the eye-catching black and navy ombre gown which glittered under the bright lights of Royal Albert Hall.
She truly dazzled in the glittering number, which remained utterly sophisticated with a round scooped neckline and three-quarter length sleeves, before it cut into a daring thigh-high split at the skirt.
Showcasing her enviably tanned and toned pins, the Oscar-winning actress boosted her frame with a pair of platform peep toe heels as she sashayed down the red carpet.
Penelope accessorised with shimmering silver drop earrings for an added touch of glamour, and left her hair in loose, tousled waves to let her naturally stunning features shine through.
Penelope stars as missionary Pilar Estravados in Murder On The Orient Express - which is based on Agatha Christie's 1934 novel of the same name - and marks the fourth adaptation of the story so far.
The story follows famed detective Hercule Poirot, who boards the famous Orient Express to enjoy some time off between cases.
However he immediately finds himself faced with a desperate oil tycoon, who begs him for personal protection, as he is fearing for his life on the famous transportation.
Following the ominous encounter, the tycoon is then found stabbed to death the following day, and Poirot is forced to investigate the other weird and wonderful characters on board, to uncover the culprit.
Penelope joins a number of Oscar winners in the film's stellar cast, including Johnny Depp, 54 and Judi, 82, as Princess Dragomiroff.
The film is a remake of the 1974 classic, and hits UK theaters on November 3 and US theaters November 10.
It's the fourth adaptation of Christie's novel - following Sidney Lumet's famous 1974 film, a 2001 CBS version, and a 2010 episode of ITV series Agatha Christie's Poirot.
Penelope was not joined at the premiere by her husband Javier Bardem - who she shares Leo, aged six, and Luna, aged four, with.
The Vicky Cristina Barcelona star recently admitted that becoming a mother changed her outlook in life and contributed in shrinking her ego.
In conversation with Gwyneth Paltrow, the pinup said: 'I'm happy to say, that my ego has gotten smaller over time.'
She continued: 'I used to be so afraid about what people were going to think of me, if I was going to be accepted, if I was going to be loved. I put a lot of energy into the perception of myself.
'When I became a mother—almost seven years ago—something very deep changed in me, where I really don’t care about a lot of the stuff I used to care about before.
'That’s part of growing up, and now I have to go through other tests that life will put in front of me. I have new fears now.'
