Samba Chanson (2002)

Zé Rocha is a director trying to shoot his first film. He dreams of making a professional movie, and starts shooting in 35mm. But as his budget begins to fade, he changes to Black-and-White, then gradually down to 16mm, Super-8 and, in the end, to his despair, to the video format. With the help of Edna Marla, producer who is searching for the Holy Grail of a genuinely 100% Brazilian celluloid; Dona Martírio, his mother, former left-wing activist; Guará Rodrigues, an underground Brazilian movie star; and Lila Lessa, who stars in a 6 p.m. soap opera, they develop strategies and outlandish plans to win the insane battle of filmmaking in Brazil.

Unfortunately the movie Samba Chanson is not yet available on HBO Max.
