Born in Paris on 1 July 1985, Lea started acting at age 18. Originally, she wanted to be an opera singer. Acting was a better choice. She has been nominated for three César awards (French Oscars) for the movies The Beautiful Person, Belle Épine and My Queen. Her success fast introduced her to international audiences. Lea comes from a well-off French family and she attended summer camps for six years in the US to hone her English. As a result, she has had no trouble appearing in English language films and her impressive regimes already includes roles in the likes of Inglourious Basterds, Robin Hood, Midnight In Paris, Mission: Impossible – Ghost Protocol, Grand Budapest Hotel and The Lobster.
She has continued to star in French films at the same time, such as the critically acclaimed and explicitly sexual, Blue Is the Warmest Colour, which netted Léa the 2013 Best Actress Palme d'Or at the Cannes Film Festival. Luckily for fans, Mademoiselle Seydoux was not in the least afraid of its full-on nudity or extreme lesbian sex scenes!
