Originating as a three-part web series, it also included appearances by Tim Russ (who directed the film), Grace Lee Whitney, Garrett Wang and Ethan Phillips. Plus, James Kirk even shows up (sort of). For a fan film, it was really quite good, and maybe it should be considered a semi-pro effort because of its credentials. It delivers an interesting alternate timeline story, and it's worth a look for Star Trek fans. You can watch the trailer below and the full film is available at YouTube at this link.
