The actress, 34, has won acclaim for her role as French-Canadian Marie-Andrée Leclerc, murderer Charles Sobhraj’s partner in crime.
But it was Leclerc’s incredible 70s wardrobe which really got people talking, from her oversized sunglasses to her colour blocked ensembles and wide leg trousers.
Jenna Coleman shared behind the scenes snaps from her incredible 70s-inspired fashion fittings from The Serpent on Instagram on Saturday

The Serpent is an eight-part series based on the real-life story of Charles, a murderer, thief and seductive master of disguise, who was a hidden darkness in the mid-70’s on Asia’s hippie trail.
Jenna spoke about the fashion on the series with Vogue magazine recently.
She said: ‘ We had lots of reference images and spoke about wanting a dark [Brigitte] Bardot vibe. In my mind, Marie-Andrée was obsessed with magazines, particularly Paris.
‘The idea was that she wanted to shed her French-Canadian identity and transform into somebody else. There’s a floatiness to her look and I brought the idea of her wearing kimonos around the house.

Transformed: In the series, a darker shirt was worn and a blue patterned headscarf was thrown into the mix
The sunglasses are incredible too, and then there’s what she wears in Paris.
‘We looked at images of Mick and looked at images of Mick and Bianca Jagger, and that’s where we got the idea for [Sobhraj and Leclerc’s] suits. I was also part-wigged because when we first meet Marie-Andrée she has quite big curly hair.’
French Canadian Leclerc began her relationship with Sobhraj aged 30 after he poisoned her male friend to ‘get him out of the way’, however Leclerc was ‘thrilled’ to meet charismatic Sobhraj.
Leclerc soon learned how immoral and corrupt her new partner was, however she still stuck by him and even turned up the music as he and an accomplice bludgeoned two victims to near-death.

Notorious con-artist Sobhrag attracted tourists and tricked them into handing over their money for his scams, and if they refused to help he poisoned them.
One of his first known victims was American tourist, Teresa Knowlton, who was murdered aged 21 after being drowned wearing a bikini by Sobhraj and his henchman Ajay Chowdhury.
However rather than running from the situation, Leclerc pretended to be the murdered victim so she was able to cash the thousands of pounds in travellers cheques they had stolen from her.
Sobhraj was first caught in 1976 when he tried to drug an entire group of French students in New Dehli and one of them caught on to his plan and handed him over to the authorities.
He spent a total of 21 years in jail in India where he was jailed for culpable homicide for poisoning a French tourist and killing an Israeli man. He was released in 1997.

During his time in prison, authorities in Thailand attempted to extradite Sobhraj and he threw a huge party for inmates and guards alike. He drugged them all with sleeping pills and managed to walk out of the prison.
He was later caught and jailed for another 10 years for the event until 1997.
The law caught up with him again in Nepal in 2004 when he was jailed for the killing of US tourist Connie Joe Bronzich in 1975.
In 2014, he was handed a second life sentence for the killing of Canadian backpacker Laurent Carriere, whose passport he had used to escape Nepal after killing the pair.
Sobhraj has now been linked to 20 murders during his killing spree.
While in jail in Kathmandu, Sobhraj married Biswas, who is 44 years his junior and the daughter of his lawyer.
Leclerc professed her innocence right up until her death aged 38, following an ovarian cancer diagnosis while imprisoned in India.
She was allowed to return to Canada upon the condition she would come back to India when her health improved.
