Playmates within cinema of the United Kingdom, is a 1922 silent comic film clip of the (then) young comedian Will Hay dressed as a school boy, and playing with a girl and some mechanical children's toys, from his theatrical revue 'Listening In'.
Introducing some clever mechanical toys, M'lita Dolores dressed as a young girl, stands on steps in front of a door - enter Will Hay dressed as a schoolboy.
Allegedly very scratchy but watchable, the clip is stored with the National Film and Television Archive.
'Listening In' was a variety show produced August 1922 by Julius Darewski at the Apollo Theatre, London.
