Clémence Poésy will be directed by Stanley Tucci in 'Final Portrait'.
Poésy has joined the cast of the movie which will be helmed by the 'Spotlight' actor in his fifth stint as a director.
The film will focus on the relationship between American art critic James Lord and his friend, Swiss painter Alberto Giacometti, whom Lord decides to sit for a painting for not realising he is totally unprepared for his demanding nature.
Poésy joins a star-studded ensemble which includes Geoffrey Rush as Giacometti, 'Monk' actor Tony Shalhoub, La Vie en Rose's Sylvie Testud and Armie Hammer.
The story has been adapted from James Lord's 1965 memoir 'A Giacometti Portrait'.
Lord will be played by Hammer, who was asked by Giamcometti to sit for eighteen days while he created his portrait.
Lord recorded the sittings and took photographs of the work in its various stages, and chronicled the relationship between Giamcometti and his muse and lover - played by Poésy - while Testud stars as his long-suffering wife.
Shalhoub will play Giacometti's brother Diego.
The film is being produced by Gail Egan and will start shooting in four weeks at Twickenham Studios and on location around London.
Speaking about the project previously Tucci told BANG Showbiz: "Next up I'm making a movie about Alberto Giacometti. I'm so excited, I've got the wonderful Geoffrey Rush playing Giacometti. I'm very happy with the script."
