Page "Star Trek VI: The Undiscovered Country" Paragraph 54

Martia was not the first shapeshifter on Star Trek, but the character was the first to be created using computer-generated digital morphing technology.

The effects, dubbed " morfs ", were more advanced revisions of the technology used for films such as Terminator 2: Judgment Day.

Animator John Berton attempted new, more complicated morfs, including moving the camera and morphing two characters talking ; special care had to be taken to line up the characters properly in plate photography.

Martia becomes Kirk while talking, requiring similar line deliveries from Iman and Shatner ; Farrar supervised the set photography for the morfs and had the actors speak their lines in sync via a loudspeaker.

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.
