A selection from the films shown in Monitor over the past two years. In this edition: Variations on a Mechanical Theme An investigation into mechanical instruments from the musical box to the automatic orchestra. 'Much of Monitor's best work has appeared among its miscellaneous short films like "Mechanical Instruments"... a kind of discursive essay which is not generally possible elsewhere in the commercial cinema world' (Sight and Sound) and George Chapman In The Rhondda Life in the Welsh mining valleys as seen by English painter George Chapman. 'Chapman's sympathy was in every canvas and model of his that we saw, as Wilfrid Owen's pity for the soldier was in his poetry.' (The Listener) Programme edited and introduced by Huw Wheldon.
