I just finished reading Star Trek: The Motion Picture: Inside the Art & Visual Effects (2020, Titan Books) by Jeff Bond and Gene Kozicki. I highly recommend this book for both fans of Star Trek (the 1979 film specifically) and also for aficionados of how motion picture visual special effects are made (or, at least, were made on now classic films like this).
I got it from the library a while back. Pretty cool book.
Star Wars visual effects veterans Douglas Trumbull and John Dykstra then had to be brought in the create nearly all of the movie’s visual effects
Only Dykstra was a Star Wars veteran. Trumbull was offered work on SW, but turned it down and did Close Encounters of the Third Kind for Spielberg instead. And before that he was known for 2001: A Space Odyssey, The Andromeda Strain (for Robert Wise), and Silent Running (Trumbull's directorial debut).
