refused to attend the ceremony. In a letter Harry sent to Jack on his wedding day to Ann, Harry stated "the only thing that could come from this day was that our parents didn't live to see this." Throughout the early years of the studio's existence, various people, including Warner's younger brother Sam, had served as buffers between Harry and Jack. The last person to serve as a buffer between the two, father Benjamin Warner, died on November 5, 1935. Following Benjamin's death, Jack and Harry were now barely on speaking terms, and were merely just business partners to one another. Jack's marriage to Ann was also arguably a huge turning point in the two brothers' fragile relationship as well; Harry's arguments with Jack were now practically on a daily basis. By the early 1950s, the brothers' long-simmering feud had risen to new heights, as Jack began spending a lot of his time in France, occasionally ignored managing the studio in favor of vacationing, gambling, and socializing with royalty, and spent studio money lavishly on 3-D films. On one occasion during this period, studio employees claimed they saw Harry Warner who was very furious at his brother Jack chase him through the studio with a lead pipe, shouting "I'll get you for this, you son of a bitch". The studio prospered post-war time, and by 1946, company payroll had reached $600,000 a week for studio employees, and the studio's net profit would reach $19,424,650.00 by the end of the year as well. During this time, Warner hired his son-in-law, Milton Sperling, to head an independent film production company for the studio. In 1947, Harry also tried to move Warner Bros. headquarters from the longtime New York building to the Burbank area, but was unsuccessful. By the end of 1947, the studio had a record net profit of $22,000,000.00, although the following year, the studio profits would decrease by 50%. During this time, the studio was a party to the United States v. Paramount Pictures, Inc. antitrust case. This action, brought by the Justice Department and the Federal Trade Commission, claimed that the five integrated studio-theater chain combinations restrained competition. The Supreme Court heard the case in 1948, and ruled for the government. As a result, Warner and four other major studios were forced to separate production from exhibition. In early 1953, the brothers finally fulfilled their end of the bargain
