Star Trek 3: The Search for Spock (1984)

And you thought that Spock was dead? Na he's chillin' on a man made planet called Genesis with 3 Klingons, a Vulcan and Phil Collins.

I've also found out what Dr. Emmit Brown got upto in between Back to the Future 1 and 2, he went into the future and posed as a Klingon badass in this film. 3/5
