Once-promising Australian filmmaker Anthony Frith lands a final shot at glory with Hollywood’s kings of B-movie schlock, the Asylum, the studio behind Sharknado. Tasked with directing a lost-world dinosaur film in suburban Adelaide on a six-day shoot and a shoestring budget, he also turns the camera on himself, filming a behind-the-scenes documentary as the chaos unfolds. Between demanding LA execs, a bewildered cast, and his own creeping self-doubt, both productions push their first-time director to the brink. Mockbuster is a hilarious and unexpectedly tender documentary about chasing the dream through the absurd hustle of genre filmmaking, but finding a different kind of success behind the scenes.
