Trivia: Director Bryan Singer (X-Men among others) makes a cameo appearance on the bridge of the Enterprise. He's a non-speaking extra. When the Reman boarding party has beamed aboard and Riker and Worf leaves the Bridge to take care of the boarding party Singer is the officer who takes over Worf's tactical station. In the audio commentary on the DVD release Nemesis director Stuart Baird points out Bryan Singer's appearance and continues 'apparently he's a big fan of Star Trek'. (01:23:25)
Trivia: At the end of the movie, B-4 starts singing, causing Picard to smile because he knows Data's memories are surfacing. This is almost identical to a scene in Voyager when the Doctor was copied onto the matrix of Dr. Zimmerman to restore his program. It ended with Kes having the identical reaction that Picard had to B-4.
Trivia: In the scene where Picard and Data are reviewing a tactical display that shows the location of five Federation vessels near enough to render assistance, the last ship on the list is the USS Archer, likely named after Capt. Jonathan Archer, commander of the USS Enterprise NX-01 in the current TV series 'Enterprise'.
Trivia: At the end of the movie, when Riker is remembering his first meeting with Data, he talks about Data trying to whistle a song on the Holodeck. This actually refers to the Next Generation pilot episode Encounter at Farpoint. While Riker can't remember the song, fans probably can - it was 'Pop Goes The Weasel.'
