Before there was a Serge Gainsbourg(Eric Elmosnino), there was a Lucien Ginsburg(Kacey Mottet Klein), who as a child during the Nazi occupation of France, shows up early to get his yellow star. Otherwise, his musician father(Razvan Vasilescu) wants him to follow in his footsteps but young Lucien has other ideas that involve an interest in painting, especially after an early encounter with a nude model(Ophelia Kolb). As an adult, he is still studying art, at least until he meets Juliette Greco(Anna Mouglalis), Dali's mistress, as his mind goes back to music where the money is.
As much as the spirited and sexy biopic "Gainsbourg: A Heroic Life" assumes the audience already knows about the work of the legendary composer and musician, it does not hurt the movie as it takes more of a psychological and expressionistic view, starting with the cool animated opening titles, as Gainsbourg is advised by his walking id(Doug Jones,) who also interacts with other characters, well into adulthood. That's when he gets to live the life he always dreamed of as a child with a panoply of beautiful women, and smoking cigarettes that make him look cool and which will also be the end of him. But if he could also make great songs like 'Bonnie and Clyde' with Brigitte Bardot(Laetitia Casta), I'm more than willing to look the other way.
