The Oil Sharks

The Oil Sharks (Les requins du pétrole) is a 1933 German drama film directed by Rudolph Cartier and Henri Decoin and starring Arlette Marchal, Vivian Grey and Gabriel Gabrio. It is the French-language version of Invisible Opponent, made with the same crew but a largely different cast and some alterations to the story line. The sets for both films were designed by the art director Erwin Scharf.
