The regular screening of old Earth films for the crew of Enterprise NX-01, organised largely by Trip Tucker as a way of keeping up morale on a long mission.
Movie night is a shipboard tradition in Star Trek: Enterprise. Classic films from Earth's twentieth century are projected for off-duty crew in the mess hall, with Trip Tucker as the most enthusiastic programmer.
The custom appears in a number of episodes. In Dear Doctor, Phlox attends a showing of For Whom the Bell Tolls and reflects on human reactions to it. In Cogenitor, Tucker shows The Day the Earth Stood Still to a member of the Vissians' third sex as part of his ill-judged effort to educate them.
In Horizon, T'Pol is persuaded to come to a screening of Frankenstein and finds unexpected parallels with the way humans first reacted to Vulcans.
