[1] As her father did not want her to become an actress, Norsa adopted the stage name Valeri in the 1950s as suggested by a friend of hers who was reading a book by French critic and poet Paul Valéry.

[2] Valeri started her career on stage in 1947, and in 1949 she co-founded the Teatro dei Gobbi, along with Luciano Salce and her future husband Vittorio Caprioli.

[2] She co-starred in such films as A Hero of Our Times (1955), The Sign of Venus (of which she co-wrote both the story and the screenplay), and Il vedovo, as well as others.

Among the major films she co-wrote, Parigi o cara (1962) is a rare case where the story is focused on her role only.

In January 2008 she played the role of Solange in Les Bonnes at Milan's Piccolo Teatro.
