The story
5SF was founded in 2005 by Brian Firenzi while he attended USC. The idea originally came from a contest organized by the Cadillac Motor Company, where five second commercials were allowed to be submitted for cars. Firenzi and friends never entered the contest. It inspired them to create "Chivalry is Dead," a five-second film where a man refuses to hold a door for a woman. Firenzi showed various other students his films, and several other creators joined him. The website, with its promise for a film every week day, was launched on October 31, 2008. More actors, writers and directors assembled in one house in Silver Lake, Los Angeles.
In February 2013, the core 5SF crew collaborated with Uproxx, releasing weekly sketches that were longer than five seconds. Usually these sketches were about three minutes.
Dude Bro Party Massacre III
Dude Bro Party Massacre III, created in 2009, was a parody of 1980s slasher films, changing the victims of the killer to men, instead of women. The next year, the idea returned to the cast, who made it into a fake trailer. In May 2013, the cast launched a Kickstarter to make Dude Bro Party Massacre into a feature-length film. By July of that year, the Kickstarter raised over $240,000. Producer Keith Calder of Snoot Entertainment matched the Kickstarter money, putting the budget for the film close to $500,000. Production began in January 2014 in Los Angeles and Big Bear, CA, and included performances from frequent 5SF guest stars Patton Oswalt, Andrew W.K., Greg Sestero from the cult film The Room, and Larry King. Production wrapped on June 23, 2014, and Dude Bro Party Massacre III made its world premiere at the Los Angeles Film Festival in June 2015. Bloody Disgusting called it "hysterical", IndieWire called it an "Instant Cult Classic", and Ain't It Cool News praised DBPM3 for its "murderously great horror satire".
