Mannix plunges into the pool, and retrieves Linda. He walks her around the corner, and they hide behind army green barrels. When the camera cuts from the pool area to the green cylindrical containers, Linda's skirt is completely dry (gone from dark pink to its original pale) but her hair is still wet; Mannix's hair that was just plastered wet against his forehead is now perfectly dry, as are his clothes. A total of two seconds in Mannix-time elapsed between the camera cuts.
When the man in the brown coat is shooting at Marcos and Linda, he fires nine times from a revolver without reloading. It is only after Mannix pulls Linda out of the pool that the man reloads.
When Mannix refuses to let Linda Marley (Leslie Parrish) leave his house, he does allow her to make a telephone call. She threatens to call the police, and Mannix tells her that the nearest precinct's number is 555-1963. She only dials six numbers (corresponding to "555-196"). The police nevertheless show up in response to her call.
The alleged fake Renoir is painted in a style typical of 1960s magazine and paperback illustration. Pierre-Auguste Renoir, as a pioneer of impressionism, used high key broken color to attain a shimmering, iridescent, atmospheric effect. His nudes were usually pleasingly plump and completely naked. Anyone with even a slight familiarity with Renoir's work could nail this TV prop as a phony.
