This episode was directed by E. Arthur Keane but the direction is credited to pseudonymous and non-existant director 'Alan Smithee'. The Directors Guild contract generally does not permit a director to remove her/his name from films. The only exception is if the product was clearly taken away from a director and recut heavily against her/his wishes in ways that completely altered the end result. In such cases, the director's name is replaced by 'Alan Smithee'. That must obviously have been the case here too, and apparantly no one was happy with the finished result as the episode remains unaired.
