Based on Romain Gary's book of the same name, this movie fascinated me with its full respect of the tiniest details mentioned in the book. It felt like I was the movie's director because of the huge similarities between what I imagined and what I watched.
Romain Kacew aka Romain Gary (Pierre Niney) tells his life story during which his mother Nina (Charlotte Gainsbourg) sacrificed everything for him to become the greatest man he could ever be: the greatest ambassador, writer or even Hitler's killer and by that France's savior during WWII.
Hats off to Gainsbourg's great accent and dialect transition from Polish to French and perfect representation of the obsessively loving mother Nina happened to be.
The director (Éric Barbier) added some later life stages of Gary which are not mentioned in the book, and by this I mean his travelling to Italy and his sickness, which I really feel is touching to show, knowing that he's telling somehow in the movie's last scene, his life story for the last time.
