on set allowing departments, such as make-up, to make immediate adjustments. Directing Enterprise once again was Allan Kroeker for the first half of "Storm Front", who had helmed the previous episode "Zero Hour". The production of the two parts intermingled over 14 days, with the second half directed by David Straiton. The initial two days of filming took place on the standing sets representing the Enterprise and the shuttlepod. The shoot moved to Stage 9 on the Paramount lot when it resumed after a weekend break, which had been set up to represent the interior of a New York City apartment. An area of the Paramount backlot was subsequently dressed to appear as exteriors in a Nazi-occupied New York City. This included a reproduction of a boxing poster previously shown in The Original Series episode "The City on the Edge of Forever", as well as a number of references to the production crew. A couple of locations which had appeared before in the franchise were shown, including a street corner shown in the Enterprise episode "Carpenter Street", The Next Generation "Time's Arrow" and the Voyager episode "11:59". A bus stop from Voyager "Non Sequitur" was also reused. Most filming of the episode's second half wasn't done on the standing sets. Scenes were shot elsewhere, including on-site shooting at Griffith Park, which was previously used in the Voyager episode "Future's End". Other locations included the re-dressed Paramount backlot, and an alleyway elsewhere on the site. A night shoot was required for a firefight sequence featuring explosions and stunt work. Additional post-production work was required to show Silik's shapeshifting. In the sequence where Archer and Silik infiltrate the alien compound, Fleck appeared without his usual Silik prosthetics—as, in the story, Silik has used his shape-shifting abilities to resemble a human. Reception Broadcast The first part of "Storm Front" debuted on October 4, 2004, at a gala evening on the Paramount lot hosted by Kevin Frazier. The screening was followed with a panel discussion featuring Coto, Braga, Kroeker, Rush, Bakula, supervising producer Peter Lauritson, and Sony executives Yasuhiko Mikami and Andrew Stucker. The fourth season of Enterprise was moved to Friday nights on UPN network. The first episode of "Storm Front" was broadcast on October 8, watched by 2.89 million viewers. When the second part was shown the following week, the number of viewers had increased to 3.11 million. Critical reception Charlie McCollum
