One absurd detail in Star Wars: Episode III - Revenge of the Sithproves that Emperor Palpatine/Darth Sidious was truly obsessed with the Death Star long before the original Star Wars trilogy—and before the Republic had even fallen. There are actually multiple sightings of the Death Star in Revenge of the Sith, although most of them are easy to miss. In addition to Darth Vader and Palpatine looking out a window and observing the early construction of the Death Star, there is also a shocking scene in which Palpatine looks at the Death Star plans in his office.
