Writing and casting Due to the impending
Writers Guild of America strike, writer and co-executive producer Maurice Hurley developed the teleplay in a day and a half from a story submission purchased by Paramount written by Deborah McIntyre and Mona Clee. Due to the strike, certain story ideas were removed from the plot including the planned first appearance of the
Borg, which was delayed until the
second-season episode "
Q Who". "The Neutral Zone" was originally intended to be the first of a two-part episode but due to the strike there wasn't enough time to write the second part and so the story was shortened. The second episode would have had the
Enterprise and the Romulans unite against the Borg. The script that was shot was a first draft and due to the writer's strike, no amendments were made. Director
James L. Conway later explained: "If there hadn't been a strike, I think it would have been a better script." It was the second episode of
The Next Generation directed by Conway, the first being "
Justice". He did not direct another episode until "
Frame of Mind" during season six. In the writers and directors' guide for the series, written by the show's creator
Gene Roddenberry prior to the first season,
Romulans were covered by one of the main writing rules that stated: "No stories about warfare with
Klingons and Romulans and no stories with Vulcans. We are determined not to copy ourselves and believe there must be other interesting aliens in a galaxy filled with billions of stars and planets." Following the perceived failure of the
Ferengi as the main villains of
TNG by the production staff, the Romulans became the main villains during the early years of the series. While the Romulans made their first
TNG appearance in this episode, they had been mentioned in "
Angel One" and "
Heart of Glory". The episode was the final one of season one to be completed, with production wrapping ten months after it began on "
Encounter at Farpoint". The episode featured an appearance by
Gene Roddenberry's production assistant
Susan Sackett as a Starfleet science officer. Her appearance was the result of winning a bet over her weight loss. She would go on to write two episodes of
The Next Generation with
Fred Bronson, "
Ménage à Troi" and "
The Game". Two of the time-displaced humans returned in
Star Trek literature, with Ralph Offenhouse appearing in
The Next Generation novel ''Debtor's Planet
as the Federation Ambassador to the Ferengi and again in the Star Trek: Destiny
trilogy as the Secretary of Commerce for the Federation. Clare Raymond made a further appearance in the Star Trek: Department of Temporal Investigations
novel Watching the Clock
as a counsellor for time-displaced people. Offenhouse, Raymond, and "Sonny" Clemmons also appeared in the two-part Star Trek: The Eugenic Wars'' by
Greg Cox, which was set prior to their appearance in this episode. Rather than individual designs for each forehead as with the
Klingons, a number of standard designs were created. The
Romulan Warbird made its first appearance in this episode. It was the final design by
Andrew Probert for the
Star Trek franchise. He had previously designed both the
Enterprise in
Star Trek: The Motion Picture and the
Enterprise-D for
The Next Generation. The double-hulled nature of the starship originated in early designs, but the wings were originally vertical rather than horizontal. The ship was deliberately made to be larger than the
Enterprise. ==Reception==
