Marion Cotillard & Marcel Cuddle On Set
The 36-year-old actress has been filming the flick in the city for several weeks, and was surprised by a special visit from her adorable son!
Earlier in the week on Monday (February 6), Marion and her Low Life co-star Joaquin Phoenix were spotted walking on set together.
In the film, Marion takes on the character of Sonja, a Polish woman who tries to emigrate to America. Look out for the film in theatres sometime this year!
