Early on in the episode, just after Picard realises what the terrorists are up to. He fights and disables one of the terrorists, a human played by Tim Russ, using a Vulcan Nerve Pinch, which he learned from Sarek in an earlier episode. It's ironic that Tim Russ would later go on to play the Vulcan Lt. Tuvok on Voyager, and use that very same move on many an occasion.

Scotty visits the bridge from "his" Enterprise (from the original "Star Trek" series) on the Holodeck. As the original set had long since been destroyed, the captain's chair and center console used in the episode was donated by a fan who had recreated a life size version of the bridge. The turbolift alcove and one of the stations was built on-set (and re-used in the DS9 episode "Trials and Tribbleations"). Everything else was made up of footage from the original series that was looped.
