 His final appearance was in "Blues Busters" in 1950, generally regarded as one of the funniest in the series.The early films such as "In Fast Company" (1946) flirted with the same humor-laced crime drama of the previous series, but they gradually shifted to all-out comedy, growing more slapstick and fantasy-oriented over the next decade.After 1950, the series began to resemble the farcical Abbott and Costello comedies—a far cry from the grim social realism of their 1930s films.
