Sophia Loren, who is making her first screen appearance since Rob Marshall's 2009 musical 'Nine' has said that working with her son Edoardo Ponti on new short film 'Human Voice', was the joy of her life.
According to the Hollywood Reporter, the 79-year-old actress said that when she started to think about it, she was too young but she kept it in her heart for a long time.
Ponti said that he along with her mother discussed about every line, every gesture.
Ponti further said that he told Loren that if they didn't rehearse, they would hit the same emotional notes over and over again.
