paco,
That film is a German copy of an original made by Sikorsky in the 1950's. The aircraft is an S-56 (H-37 Mojave) as can be told by the position of the tail rotor and the shape of the vertical fin. The scene below is also recognizable, the river with the distinctive island is the Housatonic River that runs by the Sikorsky Stratford, Connecticut factory. I recognize Pope's Island in the river, the helo is right over the plant.
