The Campbell Playhouse (1938–40) is a live CBS radio drama series directed by and starring Orson
Welles. Produced by Welles and John Houseman, it was a sponsored continuation of The Mercury Theatre on the Air. The series offered
hour-long adaptations of classic plays and novels, as well as adaptations of popular motion pictures. When Welles left at the end
of the second season, The Campbell Playhouse changed format as a 30-minute weekly series that ran for one season (1940–41).
