Just finished watching "Wrath of Kahn" and over the past 30 years I have forgotten just how great of a film it was. I was espically impressed with the part of Saavik played by Kristie Alley, I thought she did a fine job in her role. Does anyone know why in Trek 4 and 5 the part of Saavik was played by Robin Curtis and did not turn into a reoccurring role for Kristie Alley.
