In 1983, Rebengiuc appeared in Dan Piţa's "Dreptate în lanţuri". The same year, he also collaborated with Piţa on "Faleze de nisip", based on a screenplay by Bujor Nedelcovici. He starred as the surgeon Theodor Hristea, who, after some of his belongings are stolen, involves himself in the inquiry and directs the interrogation of a seemingly innocent man. The subtle criticism of authorities became a matter of scandal: just days after "Faleze de nisip" premiered, Nicolae Ceauşescu spoke in front of Romanian Communist Party officials in Mangalia, singling it out from breaking with the ideological requirements; as a result, it was banned from cinemas.
