I have a question to throw out there: Which Star Trek episodes are homages to (or rip-offs of) other books, movies or TV shows?
For example, "Balance of Terror" is famously based on the Robert Mitchum movie The Enemy Below.
Not necessarily looking for just TOS instances of basing an episode on another source. For example, "Inter Arma Enim Silent Leges" from DS9 is a lot like John Le Carré's The Spy Who Came in from the Cold.
What are some others?
