Problem: Irving Grant Thalberg (May 30, 1899 - September 14, 1936) was an American film producer during the early years of motion pictures. He was called "The Boy Wonder" for his youth and ability to select scripts, choose actors, gather production staff, and make profitable films, including Grand Hotel, China Seas, Camille, Mutiny on the Bounty, and The Good Earth. His films carved out an international market, "projecting a seductive image of American life brimming with vitality and rooted in democracy and personal freedom," states biographer Roland Flamini.

In 1929, MGM released fifty films, and all but five showed a profit. Of those that failed, Hallelujah in 1929 was also a gamble by Thalberg. When King Vidor, the film's producer and director, proposed the idea to Thalberg of a major film cast, for the first time, exclusively with African Americans, he told Thalberg directly, "I doubt that it will make a dollar at the box office." Thalberg replied, "Don't worry about that. I've told you that MGM can afford an occasional experiment."  By the early 1930s, a number of stars began failing at the box office, partly due to the Great Depression that was now undermining the economy, along with the public's ability to spend on entertainment. Thalberg began using two stars in a film, rather than one, as had been the tradition at all the studios, such as pairing Greta Garbo with John Gilbert, Clark Gable with Jean Harlow, and William Powell with Myrna Loy. After experimenting with a few such films, including Mata Hari in 1931, which were profitable, he decided on a multi-star production of another Broadway play, Grand Hotel, later that same year. It had five major stars, including Garbo, Joan Crawford, John Barrymore, Lionel Barrymore, and Wallace Beery. "Before Thalberg," writes Vieira, "there was no Grand Hotel in the American consciousness." The film won the Oscar for Best Picture in 1932.  Thalberg went against consensus and took another risk with The Great Ziegfeld (1936), costarring Luise Rainer. Although Louis B. Mayer did not want her in the role, which he felt was too minor for a new star, Thalberg felt that "only she could play the part", notes biographer Charles Higham. Shortly after shooting began in late 1935, doubts of Rainer's acting ability emerged in the press. However, despite her limited appearances in the film, Rainer "so impressed audiences with one highly emotional scene" that she won the Academy Award for Best Actress.  After her winning role in The Great Ziegfeld, Thalberg wanted her to play a role that was the opposite of her previous character, for The Good Earth (1937). For the part as a Chinese peasant, she was required to act totally subservient to her husband, being perpetually huddled in submission, and barely spoke a word of dialogue during the entire film. Rainer recalls that Mayer did not approve of the film being produced or her part in it: "He was horrified at Irving Thalberg's insistence for me to play O-lan, the poor uncomely little Chinese peasant." However, she again won the Oscar for Best Actress, becoming the first actress to win two consecutive Oscars, a feat not matched until Katharine Hepburn's two Oscar wins thirty years later.

What kind of risks did he take?

Answer with quotes: Hallelujah in 1929 was also a gamble by Thalberg.

Question:
James Buchanan Jr. was born in a log cabin in Cove Gap, Pennsylvania (now Buchanan's Birthplace State Park), in Franklin County, on April 23, 1791, to James Buchanan, Sr. (1761-1821), a businessman, merchant, and farmer, and Elizabeth Speer, an educated woman (1767-1833). His parents were both of Ulster Scottish descent, the father having emigrated from Milford, County Donegal, Ireland, in 1783. One of eleven siblings, Buchanan was the oldest child in the family to survive infancy.
In March 1860, the House created the Covode Committee to investigate the administration for evidence of offenses, some impeachable, such as bribery and extortion of representatives in exchange for their votes. The committee, with three Republicans and two Democrats, was accused by Buchanan's supporters of being nakedly partisan; they also charged its chairman, Republican Rep. John Covode, with acting on a personal grudge (since the president had vetoed a bill that was fashioned as a land grant for new agricultural colleges, but was designed to benefit Covode's railroad company). However, the Democratic committee members, as well as Democratic witnesses, were equally enthusiastic in their pursuit of Buchanan, and as pointed in their condemnations, as the Republicans.  The committee was unable to establish grounds for impeaching Buchanan; however, the majority report issued on June 17 exposed corruption and abuse of power among members of his cabinet, as well as allegations (if not impeachable evidence) from the Republican members of the Committee, that Buchanan had attempted to bribe members of Congress in connection with the Lecompton constitution. (The Democratic report, issued separately the same day, pointed out that evidence was scarce, but did not refute the allegations; one of the Democratic members, Rep. James Robinson, stated publicly that he agreed with the Republican report even though he did not sign it.)  Buchanan claimed to have "passed triumphantly through this ordeal" with complete vindication. Nonetheless, Republican operatives distributed thousands of copies of the Covode Committee report throughout the nation as campaign material in that year's presidential election.
