I am always amazed when I watch STAR TREK IV: THE VOYAGE HOME. I had read that it was in Shatner's contract that Paramount Pictures paid for a new hair piece for each new Trek movie they did. In THE VOYAGE HOME towards the end there is a scene where William is swimming underwater and you get some real good close ups of him and his hair underwater. If you were to tell me he wore a piece after watching that movie I would say you are nuts. Impossible! That movie came out in 1986 and damn, those underwater scenes really did show how good of a piece he had. The best money could buy!
