Input: Consider Input: Passage: McGillivray returned to Montreal in 1793 and then took a trip to Scotland and England. He was now a partner in McTavish, Frobisher & Co., who controlled the NWC. With John Gregory, he was sent to manage the company's huge depot at Grand Portage, stirring jealousy among some of the other partners. When Joseph Frobisher retired in 1798, McGillivray took his place. He set up an agency at New York City to get around the East India Company's monopoly enabling them to trade with China. He was closely involved too with the firm of McTavish, Fraser & Co., at London, managed by another relation of his uncle's, John Fraser. In 1803, he helped organize the move of the NWC's main depot from Grand Portage to Thunder Bay. All this time he was dealing with relations with the Hudson's Bay Company and the splinter XY Company that had broken away from the NWC, led by John Richardson.

Input: Consider Input: Passage: Williamson's early film work included roles in M*A*S*H (1970) and Tell Me That You Love Me, Junie Moon (1970). He portrayed an escaped slave who flees westward in The Legend of Nigger Charley (1972). He played the role of an African-American gangster in the film Black Caesar (1973) and its subsequent sequel, Hell Up in Harlem (also 1973). Williamson also starred in the 1975 western film Boss Nigger, in which he played the title role. After this he appeared as an actor in several films, most of which are considered to be of the "blaxploitation" genre. Williamson starred alongside Peter Boyle and Eli Wallach in the movie Crazy Joe (1974). In 1974, Williamson was selected by the ABC television network as a commentator on Monday Night Football to replace Don Meredith, who had left to pursue an acting and broadcasting career at rival network NBC. Williamson was used on a few pre-season broadcasts, but was quickly declared unsuitable by ABC. He was relieved of his duties at the beginning of the regular season, becoming the first MNF personality not to endure for an entire season. He was replaced by the fellow former player (and fellow Gary, Indiana, native) Alex Karras.
