Mario Lanza was an American tenor and actor. He was a Hollywood film star popular in the late 1940s and the 1950s. Lanza began studying to be a professional singer at the age of 16. After appearing at the Hollywood Bowl in 1947, Lanza signed a seven-year film contract with Louis B. Mayer, the head of Metro-Goldwyn-Mayer, who saw his performance and was impressed by his singing. Prior to that, the adult Lanza sang only two performances of an opera. The following year (1948) he sang the role of Pinkerton in Puccini's Madama Butterfly in New Orleans.
