Over the years my 1976 film ‘The Girl Chewing Gum’ has gradually acquired an extra layer of meaning - a work that originally documented the present day looks now, especially to the young, like an archaic record of a long-lost world. Acknowledging this transition, ‘The Man Phoning Mum’ combines the original film with contemporary footage shot in the same locations, enabling chance encounters between the passers-by of 1976 and their present-day counterparts.
