Cross-dressing in film and television: Cross-dressing in motion pictures began in the early days of the silent films.  Charlie Chaplin and Stan Laurel brought the tradition of female impersonation in the English music halls when they came to America with Fred Karno's comedy troupe in 1910.  Both Chaplin and Laurel occasionally dressed as women in their films.  Even the beefy American actor Wallace Beery appeared in a series of silent films as a Swedish woman.  The Three Stooges, especially Curly (Jerry Howard), sometimes appeared in drag in their short films.  The tradition has continued for many years, usually played for laughs.  Only in recent years have there been dramatic films in which cross-dressing was included, possibly because of strict censorship of American films until the mid-1960s.  One early exception was the murderer, a transvestite who wears particularly frilly dresses and petticoats, in Alfred Hitchcock's British thriller "Murder! ".
