Things that drive me mad.

You will note that this audience is sitting in a theater watching, we assume, a 3-D movie. But the photo is faked because movies were not watched with two-color glasses, but with single tinted glasses with polarized lenses. It never happened, at least not enough to suggest it was ever even close to standard, yet so many advertisers, like Discover Card,  keep using visuals like this. Are they stupid or just don't care about accuracy? In the early days of 3-D—prior to 1948— theaters may have used such glasses (which I believe are called anaglyph) for short films and novelty features. . But with the Golden Era of 3D cinematography in the 1950s polarized lenses, not bi-color glasses, were used for every single feature length movie in the United states and all but one short film.  In the 21st century,polarization  systems continue to dominate the 3-D scene. Were bi-color lenses ever used in theaters? Yes, but rarely. In the 60s and 70s some classic films were converted to anaglyph for theaters who couldn't afford polarization. Also one uses the analglyph system for television. But theaters do not use paper glasses with red and blue lenses and when advertisers show faked photos that suggest they do it drives me nuts.
