Star Trek: 10 Things You Didn't Know About Zephram Cochrane
8. One Day Enterprise
James Cromwell's appearance in Broken Bow was more than a welcome delight for Trek fans.
Suited up and a lot soberer than viewers had seen him before, Cochrane's recorded address is used as part of the launch of the NX-01 Enterprise.
Behind the scenes, James Cromwell was only part of the production for a single day and even more precisely just a few hours. Requiring little makeup and performing just one piece of dialogue, the actor was done, dusted, and home for lunch. Fun fact hunter fans, he arrived at 7.30am on June 22, 2001, and was gone by 11.30am. He would also be uncredited for the appearance in the episode.
In-universe, the opening of the Warp Five facility in 2119 is supposed to take place just a single year before Cochrane's disappearance. This mystery would take 150 years to resolve with his discovery by the USS Enterprise.
Cochrane's impact on Enterprise also extended further in that his address to Princeton University alluded to the true events of first contact with the Vulcans, which was nearly derailed by a race of cybernetic beings from the future who were defeated thanks to a group of humans from that same future.
