The Silver Shamrock Androids are featured in the film Halloween III: Season of the Witch.
The androids were created as henchmen by Conal Cochran. They seek and destroy anyone who could reveal his evil plans to kill the children on Halloween. The androids have superhuman strength, able to pull a man's head off with their bare hands.
One android was played by Dick Warlock, who also played Michael Myers in Halloween II.
