Kirk's fight scene with Martia in the form of Kirk was mostly filmed with a double dressed in similar clothes; in the majority of the shots the camera allowed only one of the combatants' faces to be seen. When Kirk talked with his double directly, two separate takes of Shatner facing opposite directions were combined, with the camera motion carefully controlled so that the resulting image looked realistic.
