thumb|Alan Ruck (2004) Alan Ruck plays Enterprise-B captain John Harriman. When approached for the role, Ruck assumed he would play an alien, saying, "Look, when I shave every day, I don't look in the mirror and say, 'Hey! There's a starship commander.'" Berman informed him that the character was from a wealthy and connected family, and was placed in command as a stepping stone to a political career. Jacqueline Kim plays Enterprise-B helmsman Demora Sulu. Kim consulted with art supervisor Michael Okuda to make sure her hand movements and manipulations of the ships' controls were consistent and accurate. Glenn Morshower played an Enterprise-B navigator; he apologized to the director for a poor first rehearsal, because as a Star Trek fan he was unused to performing along with actors he had idolized for years.
