cargo as needed. Back on Enterprise, Commander Tucker arranges a movie night for the crew featuring the Frankenstein film trilogy, and invites Sub-Commander T'Pol. She eventually consents, and finally finds in the film an insightful view into historical human-Vulcan relations. Meanwhile, Mayweather makes his intended modifications without permission, resulting in a confrontation when Paul finds out. The ship comes under further attack from an alien vessel, and Paul offers up the cargo as planned. The aliens refuse and demand the vessel as well. Left without any other option, Paul tells Mayweather to reinitiate the modifications and to detach the command module from the cargo section. They soon disable the alien ship. The brothers reconcile and Mayweather leaves, promising to visit again soon. Production In an interview conducted towards the end of the first season of Enterprise, Anthony Montgomery suggested that it would be good to see Travis Mayweather's parents make an appearance in the show. Montgomery was pleased when this came true in "Horizon", saying, "It was really a touching episode for me, you get a feel of how hard it was for Travis to leave the family and join Starfleet." Production began on January 28, 2003 and lasted for seven days. The first three days of filming took place on the Enterprise standing sets. The second day in particular took place mostly on the set for the gravity neutral "sweet spot" first seen in the Enterprise pilot, "Broken Bow". The main cast, with the exception of Montgomery, were only required for the first three days. Montgomery filmed his scenes over the course of all seven days along with the guest cast. Several sets were created on a soundstage to appear as the Horizon. These included the bridge of the cargo ship, a cargo hold, Mayweather's old quarters, a mess hall, and a variety of corridors. The Horizon itself was rendered using computer-generated imagery and was to appear as a similar type of cargo vessel to that seen in season one's "Fortunate Son". Nicole Forester, who previously played a Dabo girl on Star Trek: Deep Space Nine, appeared in "Horizon" as Nora. Corey Mendell Parker and Joan Pringle both made their Star Trek debuts in this episode. The episode was written by André Bormanis, who had previously written episodes of Star Trek: Voyager and was the story editor for Enterprise during the first and second seasons.
