The old black-and-white movies were filmed at 16 frames per second. When old movies are shown on modern projectors, which run at 24 frames per second, it gives them that comedy appearance. To create the comedy look in the old days they filmed at about 8 frames per second.
It happened to be a movie star of black-and-white films that signed the first million-dollar movie deal: Charlie Chaplin. He epitomized the black-and-white silent movie era. He is also known for witty quotes: “Words are cheap. The biggest thing you can say is ‘elephant’.” And, “A day without laughter is a day wasted.”
Charlie Chaplin’s own life was portrayed excellently by Robert Downey Jr in the movie called Charlie Chaplin for which Downey was nominated for an Oscar Best Actor in a Leading Role in 1993.
