Watch it via YouTube.  This is the only COLOR footage known to exist of Pepito in his famous clown costume. Pepito is the clown in the green coat, on the left side of the screen, in the box, during the “trial” portion of the clip.  Look at the “lobby card” photo of Ginger Rogers at the top of this page.  Pepito is clearly visible in the upper left, leaning forward out of the jury box, wearing his trademark clown suit and his tall black hat with flowers.  Lobby cards were small movie posters that were placed around the lobby of the theater, with a variety of photos from the feature presentation.

LADY IN THE DARK
(1944, United States) Directed by Mitchell Leisen

Leisen, a superb visual stylist and former costume designer, was a natural to adapt for the screen the hit 1941 musical about a troubled woman fashion editor who undergoes psychoanalysis. At the time, Lady in the Dark's story was a revolutionary idea, as was the Broadway producers' decision to stage Moss Hart's book as a straight play, reserving the musical numbers by Kurt Weill and Ira Gershwin for the heroine's dream sequences. Leisen's movie version honors this concept, although Paramount studio chief Buddy DeSylva, himself a former songwriter, insisted Leisen substitute songs by other composers for some of Weill and Gershwin's originals. The film's best number, The Saga of Jenny, sung by Ginger Rogers in an elaborate circus setting, is unadulterated Weill and Gershwin, however.
