The actors are all amateur dramatic artists and members of the Lisbon University Faculty of Law's Students Union. The television crew 'filming' the demonstration is not seen, and the voice-over commentary is uncredited. The film was made in the wake of end 1960s violent demonstrations in the very campus where the film takes place. At the time the film was made, there was only one TV broadcasting station in Portugal, and it was Government owned.
