His 2013 film '' Blue Is the Warmest Colour '' won the '' Palme d'Or '' and the FIPRESCI Prize at the 2013 Cannes Film Festival . Several days later a controversy erupted about Kechiche 's work methods ; technicians on the film accused him of harassment , unpaid overtime and violations of labour laws . The two main actresses , Léa Seydoux and Adèle Exarchopoulos , who were also awarded the '' Palme d'Or '' , had complained about Kechiche 's behaviour during the shooting but later , in an extensive interview , claimed that although he was difficult to work with it had been worth it , as he was a great filmmaker . The film also won Best International Independent Film at the British Independent Film Awards in 2013
