Oh blimey, forgot about this! The answer to mine was 'Star Trek: The Motion Picture', made with the planned cast for the aborted series 'Star Trek Phase Two'. Ten years later a new series (TNG) was made after all but the original cast was too old and they had killed the new onws in the first film! Riker is exactly the same as Decker from the first film for that reason- same character concept, different name.
As for your question, Minxy, I shall think about it...
