Star Trek Phase 2 was originally planned as a new TV series, but was cancelled in favor of making the first Star Trek film.
The cancellation of Star Trek Phase 2 paved the way for the success of the Star Trek films, The Next Generation, and Voyager.
The letter-writing campaign organized by fans saved the original Star Trek series from cancellation.
The Phase 2 sets and designs were repurposed for the Star Trek motion picture.
The legacy of Star Trek Phase 2 lives on in the dedicated and enthusiastic fanbase known as trekkies.
