The Invention of Love (1965)

A couple is pursued by the police and citizens of a city for the crime of having invented love. In every corner of the city, on the walls of the bars, on the doors of public buildings, in the windows of the bus, even that wall ruined through radio ads and detergents in the small shop window, where no one enters the lobby of the railway station which was the home of our hope of escape, a poster denounces our love.

Unfortunately the movie The Invention of Love is not yet available on HBO Max.
