At age six, Anna Maria sang in a concert on the Isle of Rhodes with a 100-piece orchestra. She performed at Carnegie Hall in New York at the age of 13. At 15, she was introduced to American film audiences in Frank Capra's 1951 musical Here Comes the Groom, which starred Bing Crosby.

Albergetti also appeared in 1955's The Last Command, which starred Sterling Hayden, and had the leading role in the western Duel at Apache Wells in 1957.
In 1959, the 22-year-old Alberghetti played the lead in "The Conchita Vasquez Story" of NBC's Wagon Train.
