Flesh feast

Flesh Feast (released in 1970, though shot in 1967) is an American horror film that features Veronica Lake in her final screen performance.

Dr. Elaine Frederick, a mad scientist, is working on developing maggots that prefer human flesh, while her services are used to make a clone of Adolf Hitler. She cooperates with the plan to resurrect Hitler as a way of exacting revenge for the death of her mother, a political prisoner executed in Ravensbrück concentration camp. While convincing everyone the flesh-eating maggots are for regeneration research, she simply wants to throw them in the resurrected Hitler’s face, which she does.
