Mirren, 73, portrays her mother, Margaret, who seems at odds with her daughter’s decision to help the boy played by Liam Gross.

“This is Nizar,” Jane says while introducing him to Margaret, who asks, “Is he from the shelter?”

Sarcastic, Jane responds, “No, I picked him up from an alleyway.”

Directed in segments by 12 directors, the film is the latest installment in the Cities of Love franchise which has spawned the films Paris, Je T’Aime and New York, I Love You.
