Within its thirty year history, from “The Cage” to Voyager, there have been nearly 300 filmed Trek adventures. Whilst these were being written and produced many ideas were discussed, plot lines planned, endings changed. Lost Voyages of Trek and The Next Generation serves as in-depth guide to the Trek episodes that never were, from Trek Classic’s “He Walked Among Us” through the scripts written for the aborted 1970’s series Star Trek II. There are also details on alternate – and never seen – feature films, including Starfleet Academy and Star Trek VII, and the lost voyages of The Next Generation. For the Trek fan these lost voyages play an integral role in the history and development of all things Trek.
