The Thunder of God (movie, 1965)

Brassac (Jean Gabin) is a drunken veterinarian who can't resist bringing home stray animals and humans. Lilli Palmer plays his long-suffering wife Marie. When he brings home the prostitute Simone (Michele Mercier), Brassac is not sure he is acting out of concern or lust. He beats up the pimp who comes looking for Simone, and Brassac is happy when she later falls in love with his neighbor, and they make Brassac a "grandfather."
