• Series Finale. Unlike the series finales for the other Trek spin-offs, this episode is only 1 hour long.
  
• This episode is a holographic simulation run by Riker during The Pegasus mission aboard the U.S.S. Enterprise NCC-1701-D. It contains many references to previous Star Trek people and events. 71 people died on the Pegasus.
  
• Brent Spiner provides his voice as Data in a communication to Troi.
  
• Shran married Jhamel and they had a daughter, Talla. Jhamel is an Aenar (from "The Aenar").
  
• The episode ends with a nice montage of Picard, Kirk and then Archer reciting the "Space, the final frontier..." monologue.
  
• Allan Kroeker also directed the DS9 finale "What You Leave Behind" and the Voyager finale "Endgame".
  
• Jonathan Frakes has appeared in all four Star Trek series since The Next Generation; as Will Riker in this episode and in Voyager's "Death Wish", and as Tom Riker in DS9's "Defiant". Marina Sirtis never appeared on DS9, but did appear in 3 episodes of Voyager as Troi.
  
• Rick Berman and Brannon Braga originally wrote this episode for the Season 3 finale when it looked like Paramount wasn't going to renew the show for a 4th season. They intended for it to be a finale for the Star Trek franchise that ran for 17 straight years starting with Next Generation.
