Pie throwing is documented in the independent films "Pie Fight '69" and "The Horribly Stupid Stunt (That Has Resulted in His Untimely Death)".

Two filmmakers unearthed footage lost since 1969 about the notorious 'pie-fight' incident that occurred outside the San Francisco Film Festival. Two dozen costumed radicals (all independent filmmakers) descended on the black ties, fox furs and red carpet with one fully laden pie truck and six cameras to record their outrageous action.
