Konga is a fun mid-sixties horror film made in Britain. It's fast, it's full of wonderfully unlikeable people, and it has a guy in a gorilla suit. What more do you need? It stars Michael Gough as the most egotistical scientist in cinema who has just come back from being lost in the jungles of deepest, darkest Africa. He returns with a small monkey, a bag full of carnivorous plants, and the claim he will show the evolutionary path between plants and animals.
Once home, he treats his trusted female companion like garbage. It's ok though, she must like it. He plants the plants and gets on with making a drug from huge plastic carnivorous plants. He then injects little Konga who turns into a man in a monkey suit. Our scientist then uses Konga to protect his tenure (killing college deans), and intellectual property (killing rival doctors). His doormat of an assistant is so smitten with the killings that she demands that he marries her.
He says yes, but he has other plans. Young, blonde plans. Finally the doormat realizes what's going on, and gives Konga a super dose. He becomes a man in a monkey suit in a very small set. Konga then picks up a Michael Gough doll and runs around London till killed. All very sad, the end.
Definitely a fun, campy time.
