 Their career of spoof filmmaking began when Friedberg's father showed Leslie Nielsen a script his son had written to parody spy films, which resulted in 1996's "Spy Hard".Thereafter, the duo worked as freelance screenwriters, selling dozens of scripts though all but one of them never went into production.They then penned the script that became 2000's "Scary Movie", though they were then credited as two of the film's six writers as their draft underwent revisions by four other authors.
