The parting of the Red Sea in The Moon of Israel (1924, dir. Michael Curtiz)
The parting effect was achieved by dumping 25,000 gallons of water down the plaster walls built on either side of the path and running the film in reverse.
Living Marble (1910, dir. Johann Schwarzer), an example of the 1910’s-era Austrian erotic film genre known as “Pikanter Herrenabend Film” (i.e. “Racy Night Films for Gentlemen”)
In this one, some men play a practical joke on a friend by having a woman paint herself white and pretend to be a nude marble statue. In this scene, the pranksters decide how to best position her, which provides a convenient excuse for placing her in a variety of revealing poses.
