Before “It’s A Wonderful Life,” Cornflakes painted white were used for snow. To avoid the “crunch,” Frank Capra used three types of snow in “It’s A Wonderful Life”: Ivory soap flakes, chipped ice, and something called foamite, which is similar to what is used in fire extinguishers today. Soapy suds can be seen in the shot of Clarence and George in the river.
