Tremors 3: Back to Perfection is a 2001 direct-to-video horror monster film directed by Brent Maddock, and is the third installment in the Tremors series featuring the subterranean worm-creatures dubbed "Graboids". It is a sequel to Tremors 2: Aftershocks. Michael Gross, Charlotte Stewart, Ariana Richards, Tony Genaro, and Robert Jayne reprise their roles from the first film. It is followed by Tremors 4: The Legend Begins.

Burt Gummer (Gross) has returned to Perfection, Nevada. Sure enough, Graboids attack again, only now they are split into graboids, shriekers and a new mutation known as ass-blasters, which are propelled into flight by combustible flatulence. Stalked by an albino sterile graboid known as El Blanco, it's up to Burt, Jack Sawyer (Shawn Christian) and other locals to save their town from destruction.
