The opening school sequence was filmed on location at Hollyfield Secondary School, Surbiton, Surrey on Tuesday March 13th 1979. The opening shot zooms in on the top floor of the Villiers Block, but the sequence was filmed in a smaller classroom in the adjacent Olsen Block (now the school library). The sequence only lasts about 3 minutes but it took an entire day to film. Hollyfield school kids were selected as extras.
Leo McKern and Nigel Havers co-star in this episode. They also co-starred in series of TV ads for Lloyds Bank in the late 1980s and early 1990s.
