Through this connection to Monteiro, she became close to many Portuguese film directors, meeting many of the leading lights at the time, such as António-Pedro Vasconcelos, Jorge Silva Melo, Solveig Nordlund, Alberto Seixas Santos, Paulo Rocha, and Fernando Lopes.
Monteiro asked her to be the assistant director on his next film, Fragmentos de um Filme-Esmola: A Sagrada Família, shot in 1972 and 1973.
In 1976 she participated in the creation of Grupo Zero, a film production cooperative, with Seixas Santos, Nordlund, Monteiro, Melo, Acácio de Almeida, and others.
Subsequently, Gil made several video documentaries, notably Maria, for the World Conference on Women, 1995, which took place in Beijing, and As Chosen, about the life and work of the painter Graça Morais.

In 2012 the Escola Superior Artística do Porto (ESAP) awarded Gil the Aurélio Paz do Reis Prize, in recognition of her cinematographic career.
