Fatal Deviation is a low-budget cult film produced and set in Trim, County Meath, Ireland. Produced in 1998, it enjoys the distinction of being Ireland's first full-length martial arts film. The film stars real-life martial arts enthusiast James Bennett. Despite proceeding straight to video without a theatrical release, Fatal Deviation has through word-of-mouth become a much sought-after release and, indeed, something of a cult classic. Admirers cite its unusual and enchanting rural setting; its extensive use of local individuals with no acting experience or training to fill key roles; the protagonist's many memorable one-liners (e.g. "Fuck you and your gun, ya prick"); and the undeniable charisma and magnetism of its star. The film is also notable for its many plot holes, continuity errors, incoherent dialogue, badly-dubbed sound effects and a scene involving the consumption of cocaine using a Dunnes Stores Value Clubcard.
