Here's a 1970s clip showing a group of French film executives sitting in a screening room and watching an old movie showing women in swimsuits. 

One of the executives calls out to the projectionist in French to cut the lights and start the film. The lights are lowered and the film begins. We see a close-up of the projector and its lens.

Old, black and white footage of women are shown. One woman, who is wearing a swimsuit and holding a paddle, is on a beach with her dog.  

In another scene, two women in swimsuits are relaxing in a boat that is being guided down a river by another woman, who is doing the paddling. 

In the third and final scene, a number of women wearing swimsuits along with summer attire are outside in the sun -- as if modeling for an off-camera photographer. One woman beams a big smile for us, the audience.
