The film is officially an adaptation of the newspaper short story 'Cerná a bílá' ('Black and White') by Zdenek Hrebík. However, the idea of a cybernetic grandmother was developed several decades earlier by Jan Werich in another short story and shortly after him by animator Jirí Trnka in his short film La grand-mère cybernétique (1962).
The film was originally to be called simply 'Babicky' ('The Grandmothers'). However, as another Czech film with a similar title ('Sestricky' / 'The Nurses' - Sestricky (1984)) was running in cinemas at the same time, the name was changed. The inspiration for the new title came from older Czech - seemingly nonsensical - titles such as Zabil jsem Einsteina, panove (1970) or Monsieur, vous êtes veuve (1971), on whose quirky style the film builds on to some extent.
Director Ladislav Rychman struggled with various health problems during the filming and was hospitalized several times. Because of this, filming was interrupted several times and the budget of the initially very inexpensive film was increased.
