During the filming of Boy on a Dolphin, Sophia Loren appeared opposite the diminutive Alan Ladd. In order to give audiences the impression that Ladd was taller than she was, Loren was required to walk everywhere in a trench.
["Sex appeal," as Loren once observed, "is 50% what you've got and 50% what people think you've got!" Loren's childhood nickname? "Toothpick". Ladd's childhood nickname? "Tiny".]
