<Li> Robert Duncan McNeill (Paris) and Roxann Dawson (Torres) have also directed episodes of Star Trek: Enterprise . </Li> <Li> Jonathan Frakes, LeVar Burton, and Andrew Robinson (Garak of Deep Space Nine) all directed episodes of Star Trek: Voyager . </Li> <Li> The sets used for USS Voyager were reused for the Deep Space Nine episode "Inter Arma Enim Silent Leges" for her sister ship USS Bellerophon (NCC - 74705), both of which are Intrepid - class starship . The sickbay set of USS Voyager was also used as the Enterprise - E sickbay in the films Star Trek: First Contact and Star Trek: Insurrection . Additionally, the Voyager ready room and the engineering set were also used as rooms aboard the Enterprise - E in Insurrection . </Li> <P> The series consists of 168 episodes, 164 of which are ~ 45 minutes in length and four of which are ~ 90 minutes in length; however, the four double - length episodes (Caretaker, Dark Frontier, Flesh and Blood, and Endgame) are sometimes erroneously counted as two each . The DVD release definitively establishes which episodes are true two - parters (examples: Basics, Future's End, Scorpion, Year of Hell) and which are double - length single - part episodes . The combined running time of all 168 episodes, including opening and closing credits for each episode, is 129 hours, 39 minutes, and 12 seconds . </P>
