Along with producer Leon Schlesinger, other members of the Warner Bros. animation studio played the live-action roles: writer Michael Maltese was the security guard, animator Gerry Chiniquy was the live-action director, and manager Henry Binder was the stagehand who tosses Porky out of the soundstage. With the exception of Schlesinger, all voices were dubbed over by Mel Blanc.
Porky Pig disguises himself as Oliver Hardy. He also makes reference to Errol Flynn. Daffy Duck makes references to Bette Davis, Fred Astaire and Greta Garbo (pronouncing the last as "Greeta").
The film being shot when Porky crashes the sound stage, taken from short subject made several years earlier, is Wonder Bar, more specifically the "Don't Say Goodnight" number. Busby Berkeley and Lloyd Bacon can be briefly glimpsed near the camera boom.
The title is based on the song "You Ought to Be in Pictures" by Dana Suesse and Edward Heyman.
