In 1989, unwitting Utah actors starred in the undisputed Worst Movie in History: TROLL 2. Two decades later, the legendarily inept film's child star unravels the improbable, heartfelt story of an Alabama dentist-turned-cult movie icon and an Italian filmmaker who come to terms with this genuine, internationally revered cinematic failure.

From Netflix:
Most people don't set out to produce a horrible film, so how exactly does it happen? This documentary about 1989's Troll 2 -- often referred to as the "worst movie in history" -- attempts to answer that question. Director Michael Stephenson, who, as a child, starred in the ill-advised horror flick, delves into how an Italian filmmaker, some unwitting actors and a dentist-turned-cult movie icon joined forces to spawn this dubious achievement.
