Similarities with Star Trek VI's ending. (spoilers)
I was watching this on TCM and when it got to the ending with the art gallery, I was thinking this reminds me of Star Trek IV: The Undiscovered County's conference assassination attempt scene. And then after the killer is stopped, it had the same twist; the killer was in disguise. (That reveal happens in the video release of ST6, not the theatrical release, IIRC)
So I guess this film is where Star Trek VI got that inspiration from.
