I'm glad to read I'm not the only one who thinks this is the best movie out all the ones with the cast from original Star Trek. "Star Trek II: Wrath of Khan" was released June 4, 1982, was a sequel to the original series episode "Space Seed" starring Ricardo Montalban. The difference in release dates between "Space Seed" and "Star Trek II" is 15 years, which is the same difference in the time in which these events are to have happened.
Ricardo Montalban did not wear a prosthetic chest. That's his real chest, folks!
