Carr's work mostly includes female lead roles in sci-fi movies. During the filming of one of her movies, Monstercon from Mars, the machine that played the Monstercon broke down in the middle of a scene. This made the director furious and he demanded that a replacement be found.
As a coincidence, the Decepticon Pretender Skullgrin was on a mission in a nearby swamp. Carr and Skullgrin met, and because of the monstrous appearance of Skullgrin's outer shell, he became an actor himself, starring as the monster in Carr's sci-fi movies.
