Thalberg was born in New York City of German immigrant parents. He had a bad heart and was plagued with other ailments all of his life. He was quite intelligent with a thirst for knowledge but, convinced that he would never see thirty, he skipped college and became, at 20, a high-level executive at Carl Laemmle's Universal Studios. In 1924 he became the #2 man under Louis B. Mayer at MGM, the biggest studio in the world. In 1927 he married the actress Norma Shearer, whose career flourished as the wife of the most powerful and respected producer in Hollywood. They had two children; Irving, Jr. and Katherine. Thalberg believed in making quality pictures, as he felt that they brought status and prestige to the fledgling industry. His fragile health gave out on Sept. 14, 1936. After his death the Motion Picture Academy created the Irving Thalberg Award, given for excellence in production.


The character of Monroe Stahr, the hero of F. Scott Fitzgerald's final novel (The Last Tycoon) was based on him. Fitzgerald also based the story, 'Crazy Sunday', on a party he attended at his home. Interred at Forest Lawn, Glendale, California, USA, in the Great Mausoleum, Sanctuary of Benediction, end of the hall, on the left hand side, the very last private room marked "Thalberg." Before marrying Norma Shearer, he was romantically linked to Rosabelle Laemmle (daughter of film mogul Carl Laemmle), actress Constance Talmadge, and socialite Peggy Hopkins Joyce. Owing to Thalberg's habit in his lifetime of not seizing the spotlight for himself, Hollywood's memorials to him after his death were relatively sedate, although heartfelt. MGM renamed their administration facility the Thalberg Building, and the Academy of Motion Picture Arts & Sciences created the Thalberg Award to acknowledge "Creative producers, whose bodies of work reflect a consistently high quality of motion picture production." Took a screen credit only once in his lifetime: He credited himself as "I.R. Irving" for a screenplay he wrote, "The Dangerous Little Demon." After director King Vidor complained to Thalberg that he was tired of shooting pictures that played in theaters for just one week, he told him about a new kind of realistic war movie he had envisioned. Thalberg was enthusiastic about Vidor's vision, and tried to buy the rights to the hit Broadway play "What Price Glory?" co-written by Maxwell Anderson and World War I Marine veteran Laurence Stallings. Since the rights to the popular anti-war play had already been acquired, he hired Stallings to come to Hollywood and write a screenplay for the new, realistic war picture that Vidor had dreamed about making. Stallings came up with The Big Parade (1925) an anti-war film that dispensed with traditional concepts of heroism, focusing instead on a love story between a Yank soldier and a French girl. After Vidor completed principal photography, Thalberg took the rough cut and previewed it before live audiences in Colorado. Although the audiences responded favorably, Thalberg decided to expand the scope of the picture as Vidor had created a war picture without many scenes of war. He had Vidor restage the famous marching Army column sequence with 3,000 extras, 200 trucks and 100 airplanes, adding about $45,000 to the negative cost of the film. After Vidor moved on to another project, Thalberg had other battle scenes shot by director George W. Hill. The result was a classic, a major hit that proved to be M.G.M.'s most profitable silent picture. The Big Parade (1925) was an example of Thalberg's perfectionism as a managing producer. Is portrayed by John Rubinstein in The Silent Lovers (1980) (TV) Is portrayed by Robert Evans in Man of a Thousand Faces (1957) He was reportedly the person who created the term "film editor" as opposed to simply "cutter." He first applied the term to Margaret Booth.
