Before playing Édith Piaf, two movies starring Marion Cotillard have featured a song by the French singer: Chloé (1996) and Love Me If You Dare (2003), both movies have "La Vie en Rose" in the soundtrack. Years later, Cotillard starred in Inception (2010), which featured another song by Piaf: "Non, Je Ne Regrette Rien".
Piaf's boyfriend was named Marcel Cerdan. Marion Cotillard's son is also named Marcel, which is a very common name in France. Cotillard later revealed that her son's name is actually an homage to a member of her family, Marcel Theillaud, not to Piaf's lover as many people assumed.
When Marion Cotillard introduced the song "Everything is Awesome" from The Lego Movie (2014) at the 87th Academy Awards in 2015, Édith Piaf's song, "La vie en Rose" was playing in the background when she took the stage.
In Christopher Nolan's "Inception" the song "Non, Je ne regrette rien" is used in the movie as a trigger song; Marion Cotillard, who plays Edith Piaf in this movie also plays the role of "Mal" in Inception
