 The character of Dax in this film (a young crew member questioned  during the search for incriminating evidence) is no relation to the  character of Dax from _"Star Trek: Deep Space Nine" (1993)_ (qv).  DS9s Dax would, at the time of this film, be in the persona of  Curzon Dax, a Federation ambassador, which is clearly not the case  for the character of this film. The name was a coincidence.
