text_A: After the purchase of United Artists, David Begelman's duties were transferred to that unit. Under Begelman, MGM/UA produced a number of hit films, and he was fired in July 1982. Out of the 11 films he put into production, by the time of his release from the studio, one film, "Poltergeist" (1982), proved to be a clear hit. Not even MGM's greatest asset – its library – was enough to keep the studio afloat. After 1982, the studio relied more on distribution, picking up independent productions, rather than financing their own projects.
text_B: Did Begelman work for MGM/UA in 1983
NO.
