I can't say enough good things about this film. First of all, the style. I'd have to ask someone who lived in that part of Brazil in 1977 but it felt just like it was filmed in Recife in 1977, in exactly the same way that Nouvelle Vague did. Spellbinding. The music was perfect, the film stock (of which I know very little) was perfect. I knew I was going to love it just a few minutes in.
The tempo was mesmerising. Very slow and reflective, which is just my thing. There's some fast-paced stuff later in the film but even that feels measured.
Dona Sebastiana, played by Tânia Maria, brilliantly played the matriarch of her small community: caring but not to be messed with. "Marcelo", played by Wagner Moura, amazed in every scene: quiet, introspective.
The Secret Agent has gone straight into my top 100 films, replacing Killers of the Flower Moon (it's a cut throat list). It looks like I've got three other Kleber Mendonça Filho films to watch now: Neighbouring Sounds (2012), Aquarius (2016), and Bacurau (2019).
