Léa Seydoux and her Blue Is The Warmest Colour co-star Adèle Exarchopoulos were reunited in Cannes as they both arrived at the festival with films this year. The duo shared the Palme d’Or award for their performances as newcomers in 2013, thirteen years later Seydoux in the race for gold again with her role in Marie Kreutzer’s In Competition entry, Gentle Monster. In the Corsage filmmaker’s latest, she plays Lucy, a pianist and mother who is horrified when her husband (played by Laurence Rupp) is investigated by police after child porn is found on his computer. The gentle monster of the title is the seemingly well-adjusted partner Lucy has seen no red flags in, and as the case progresses she experiences rollercoaster emotions of having lived with, and loved, a predator.

The film was initially inspired by a newspaper article Kreutzer read, but gained added resonance when Florian Teichtmeister, the actor who played Emperor Franz-Joseph in Corsage, was found guilty of possessing child porn. Kreutzer told journalists at the press conference in Cannes that she then felt this became more of a reason to create the film and address the subject matter. Seydoux told the conference that the emotionally-charged role was a challenge but a gratifying one. ‘She goes through different states of emotion at the same time as the spectator, you’re totally with her and you feel total empathy,’ she said of her character. ‘You discover the film through her. [In playing her] I tried to live in the spur of the moment and be in the state of total empathy.’ Seydoux was also nervous of singing on camera for the first time in her career, and learnt to play the piano. The film was rapturously received at its premiere, before which Greg Williams shot Seydoux at the Majestic Hotel.

The actor also has Arthur Harari’s body-swap drama The Unknown at the festival, in which she plays a woman who has a one night stand with a man and when she awakes the two have swap consciousnesses. As David, trapped in her body, Seydoux’s character questions identity and gender roles. The two films are vastly different projects but speak to audiences about pertinent themes. As Seydoux told Variety this week; ‘with the fakeness of cinema, you can make the truth appear.’
