With the release of the new Star Trek film, there was bound to be a rash of re-releases of the stuff that went before. And, well, why not? With over four decades of material to choose from, all of those who hadn't gone before will likely want to catch up.
Star Trek: Motion Picture Trilogy is one of those releases. It is a trilogy in a sense in that each one of the films leads up to the next and they all focus on the Kirk/Spock relationship. While it would have been nice to have the first Star Trek movie released with these three for completeness (actually it would have been nicer to have all six, but that is a different story), the first didn't really tie in together like these three do.
The Wrath of Khan Released in 1982, this is actually a continuation of a story that first aired in the original series called "Space Seed." It ended up with Khan and his group being set down on a planet called Ceti Alpha V. Now, 15 years later, Chekov and the captain of the USS Reliant beam down to a planet they believe to be Ceti Alpha VI to investigate the plausibility of using it for the Genesis project. It is really Ceti Alpha V and they find Khan and what remains of his crew.
Because of their superior intellect and strength, Khan and his group take over the Reliant, find out about the Genesis project, and are now out to steal it. Khan, in his arrogance, is also out to get back at Kirk for banishing him to that desolate planet and causing the death of his wife.
This is an interesting and well done film in that it not only pits Kirk against Khan again to see who can best the other in playing a cat and mouse game, but it also shows Kirk fighting with himself between wanting to be back at the helm of the Enterprise, but also dealing with middle age problems like failing eyesight as well as not always having the most sound judgment. Kirstie Alley is introduced in this film as Saavik, a Vulcan Lieutenant who does a very good job.
