Four minutes are enough to sum up the essence of a mother, the Ga of the title and the filmmaker’s own mother. Margaret Tait tells us of antelopes, buffalos and Vikings… whilst presenting an old lady running after the rainbow, carefully unwrapping a sweet, tending to her flowers, dancing and reading. All of this is through discontinuous shots, which is so typical of Tait, who spoke of this film as an “abstract exercise without the grammar of film, with shots linked just by subject, or by colour and only rarely by movement”.
