The first re-airing of this episode featured additional scenes that were featured in the trailer, including shots of Suliban soldiers searching Enterprise and Tucker pushing one of Silik's officers in defiance.
During "Enterprise"'s first run it was the most special effects-laden television show on the networks, with a reported 2,700 effects shots in the first season alone. Roughly 300 in the two hour pilot and an average of 100 per episode. Season Two surpassed this number with a reported 2,900 visual effect. The average budget for each episode of Enterprise in its first season was $3,500,000. Due to both the success of the show and more creative technology required for further seasons, the budget was increased to $5,000,000 starting with "Shockwave Part II".
This is listed as one of the "Ten Essential Episodes of Enterprise" in the 2008 reference book "Star Trek 101" by Paula M. Block and Terry J. Erdmann.
Gary Graham (Soval) was once considered for the roles of both Commander Benjamin Sisko and Captain Katherine Janeway, before the decision was made for Janeway to be female and for Sisko to be African-American.
Trek semi-regulars Foundation Imaging (a company which had been working in special effects since its involvement in the first season of sci-fi series Babylon 5 (1993)) was dropped on the debut of Enterprise's second season. Instead, Eden FX took over all the effects work to become the new leading effects house for the TV series.
