Maria Pia Casilio (5 May 1935 - 10 April 2012) was an Italian film actress, best known for major roles in Umberto D. and An American in Rome.[1]
Born in San Pio delle Camere, L'Aquila, Casilio was quite active between 1952 and 1960, usually filling roles as a querulous and naive small-town girl.[1] After her marriage with voice actor Giuseppe Rinaldi, she semi-retired from acting.[1] On the Criterion Collection DVD release of Umberto D. Vittorio De Sica comments she was a lucky charm to have her in his films.
