John Travolta, Brian De Palma, Nancy Allen and cast and crew wearing potato noses on the set of Blow Out, 1981. Assistant cameraman Michael Gershman said “John complained that Vilmos’s lighting made him look like he had a potato nose. So I sent out for a large bag of spuds, had my assistant cut them in half and hollow them out. We attached the elastic from dust masks and everyone had a potato nose. John walked on set and didn’t notice at first and then broke up.”
