Thomas remained in "Our Gang" when the series changed production from Hal Roach Studios to Metro-Goldwyn-Mayer in 1938. Thomas was the only cast member to appear in all 52 of the MGM-produced entries and was the only holdover from the Hal Roach era to remain in the series until its end in 1944. By 1940, Thomas had grown out of his speech impairment, and with Lee having been replaced by Robert Blake, Thomas's Buckwheat character was written as an archetypal black youth. He was twelve years old when the final "Our Gang" film, "Dancing Romeo", was completed in November 1943.
