Brief Description  The Mighty Gorga (1969) is an independent, low-budget American adventure fantasy film directed by David L. Hewitt, notorious among B-movie enthusiasts as one of the lowest-quality King Kong knock-offs ever made. Shot on a minuscule budget primarily in California's Bronson Canyon and Simi Valley, the film is famous for its heavy use of stock footage, highly visible special effects blunders, and a giant ape costume that only consists of a mask and the top half of a suit.

Plot:
The story follows Mark Remington (Anthony Eisley), a struggling circus owner facing imminent bankruptcy and a hostile takeover by a massive corporate rival. In a desperate bid to save his business, Remington travels to Africa to track down a legendary great white hunter, "Tonga" Jack Adams (Kent Taylor), who once claimed to know the location of a mythical, 50-ton giant gorilla named Gorga. Upon arriving in Africa, Mark finds that Tonga Jack has gone missing in the jungle. He teams up with Jack’s daughter, April Adams (Megan Timothy), who is running a local zoo that is also facing financial repossession. Together with their foreman George (Lee Parrish), they mount an expedition into the deep Congo jungle to find Jack and capture the giant ape to secure their financial futures. Along the way, they must contend with Dan Morgan (Scott Brady), a greedy, rival hunter trying to sabotage them.

The expedition eventually discovers a hidden, prehistoric plateau. On this plateau, dinosaurs and other ancient beasts coexist alongside Gorga, who is actively worshiped as a god by a local tribe. After being captured by the native tribe—who have also imprisoned Tonga Jack—the group is sentenced to be sacrificed. However, Gorga attacks the village, disrupting the ritual and allowing the group to escape. While fleeing, the team takes refuge in a hidden cave where they discover an unexpected ancient treasure and fight off one last cave monster before safely escaping the plateau. Due to the severe lack of funding, the crew could only afford half of a gorilla costume. As a result, Gorga is only ever filmed from the waist up. The matte lines separating the ape from the background are highly visible, and critics often note it looks precisely like a man in a cheap mask.
