The show also featured an appearance from TNG character Counselor Troi, and the voices of TNG characters Data and Picard, along with the voice of Star Trek original series star William Shatner.
Brannon Braga also noted that he and Rick Berman really thought they were doing justice, not only to Enterprise, but the whole of the Star Trek TV franchise by ending the show the way they did.
The coming 2005-2006 television season was slated to be the first in 18 years that wouldn’t have new Trek on the air, and they wanted to pull as much history of the franchise together as possible, seeing as how they realized that there might not be new Trek on TV for quite a while.
