20 Things You Didn't Know About Star Trek IV: The Voyage Home
14. Reuse Props And Keep The Budget Down
Star Trek IV both continued and began the process of reusing props to keep the budget under wraps. One of the new items made for the film, that of the 'pool table' that is visible in Starfleet Headquarters, would go on to become the main table seen in Engineering in all seven seasons of Star Trek: The Next Generation.
However, that was not all. The USS Saratoga, shown in the opening scene of the film, is a redress of the filming model of the USS Reliant from Star Trek II: The Wrath of Khan. The bridge set itself was a dress of the bridge of the USS Grissom, from Star Trek III. That set was a redress of the bridge of the Enterprise 1701 from The Motion Picture, The Wrath Of Khan, and The Search For Spock.
There were many other props that were reused in the film, including half of the screens on the Bird of Prey, yet of all - it remains the pool table that is the most easily recognizable to most Trekkies today.
