The film adaptation of "The Wiz" had been a $24 million production, but upon its October 1978 release, it earned only $21,049,053 at the box office. Though pre-release television broadcast rights had been sold to CBS for over $10 million, the film produced a net loss of $10.4 million for Motown and Universal. At the time, it was the most expensive film musical ever made. The film's failure ended Ross's short career on the big screen and contributed to the Hollywood studios' reluctance to produce the all-black film projects which had become popular during the blaxploitation era of the early to mid-1970s for several years.
