Editing Hey Arnold! (section)

==Production==
[[Craig Bartlett]], the show's creator, was born in Seattle, Washington, which he used as inspiration for the backdrop of ''Hey Arnold!''. He graduated from Anacortes High School and obtained a degree in communications from [[The Evergreen State College]] in [[Olympia, Washington]].<ref name="SeattlePost">{{cite web|url=http://www.highbeam.com/doc/1G1-64672808.html|archive-url=https://archive.today/20130125213440/http://www.highbeam.com/doc/1G1-64672808.html|url-status=dead|archive-date=January 25, 2013|title='Hey, Arnold!'

In 1987, Bartlett relocated to Los Angeles, where he joined a team developing claymation [[cutaway (filmmaking)|cutaways]] for the television program ''[[Pee-wee's Playhouse]]''. The short segments centered on a character named Penny and her friend Arnold. Bartlett later made three ''Arnold'' shorts: ''Arnold Escapes from Church'' (1988),<ref name=NYT1988>{{cite news|last=James|first=Caryn|title=Review/Film; Animated Works From All Over|url=https://www.nytimes.com/1988/10/14/movies/review-film-animated-works-from-all-over.html|work=[[The New York Times]]|access-date=January 27, 2014|date=October 14, 1988|archive-date=March 5, 2014|archive-url=https://web.archive.org/web/20140305141321/http://www.nytimes.com/1988/10/14/movies/review-film-animated-works-from-all-over.html|url-status=live}}</ref> ''The Arnold Waltz'' (1990),<ref name=Deseret1990>{{cite web|last=Hicks|first=Chris|title=Film review: XXII International Tournee of Animation, The|url=http://www.deseretnews.com/article/700002051/XXII-International-Tournee-of-Animation-The.html?pg=all|work=[[Deseret News]]|access-date=January 27, 2014|date=May 8, 1990|archive-date=February 19, 2014|archive-url=https://web.archive.org/web/20140219040114/http://www.deseretnews.com/article/700002051/XXII-International-Tournee-of-Animation-The.html?pg=all|url-status=dead}}</ref><ref name=AWN1990>{{cite web|last=Bevilacqua|first=Joe K.|title=Craig Bartlett's Charmed Past Life|url=http://www.awn.com/mag/issue3.9/3.9pages/3.9bevilacquabartlett.html|magazine=Animation World Magazine|access-date=January 27, 2014|date=December 1998|archive-date=June 28, 2009|archive-url=https://web.archive.org/web/20090628142324/http://awn.com/mag/issue3.9/3.9pages/3.9bevilacquabartlett.html|url-status=live}}</ref> and ''Arnold Rides a Chair'' (1991), the latter aired as a filler short on ''[[Sesame Street]]'' in 1991. The same year, ''Arnold'' comic strips also appeared in ''[[Simpsons Illustrated]]'' magazine by Bartlett's brother-in-law [[Matt Groening]], the creator of ''[[The Simpsons]]''.

Bartlett later joined the staff for ''[[Rugrats]]'', where he served as story editor for three years. In 1993, he teamed up with five writers from ''Rugrats'' to develop animated projects for Nickelodeon.<ref name="SeattlePost" /> These meetings were generally difficult and the writers became frustrated; Bartlett recalled: "Our ideas were OK, but such a large and motley group couldn't get far at pitch meetings. Network execs got [[migraine]]s just counting us coming in the door."<ref name="SeattlePost" /> As a last resort, Bartlett played the ''Penny'' tapes, intending to highlight the Penny character. However, the executives were more impressed by Arnold, despite his status as a minor character.<ref name="SeattlePost" /> After the meeting, the group began developing Arnold, creating his personality. Bartlett stated: "We did a lot of talking about who Arnold is. We came up with a reluctant hero who keeps finding himself responsible for solving something, making the right choices, doing the right thing."<ref name="SeattlePost" /> After creating ideas for Arnold, Bartlett began work on the supporting characters, drawing influence from his childhood: "A lot of the characters are an amalgam of people I knew when I was a kid. The girls in ''Hey Arnold!'' are girls that either liked or didn't like me when I was in school."<ref name="How" />

In 1994, Bartlett began work on the pilot episode of ''Hey Arnold!''. A year later, the network decided to begin work on the series.<ref name="How" /> The ten-minute pilot episode, titled ''Arnold'', was shown in theaters on July 10, 1996, before [[Nickelodeon Movies|Nickelodeon's first feature-length film]], its adaptation of ''[[Harriet the Spy (film)|Harriet the Spy]]''.<ref name="SeattlePost" /> Apart from the animation style, Nick's Arnold wears a sweater, with his plaid shirt untucked (resembling a [[kilt]]). Only Arnold's cap remains unchanged from his original clay-animation wardrobe.

''Hey Arnold!'' was Nickelodeon's first animated series to feature kids voiced by actual children instead of adults. As a result of this, many of the boy characters, including Arnold himself, were recast at least once throughout the show's run, due to the child actors reaching puberty. One notable exception to this was [[Jamil Walker Smith]], the voice of Gerald. After Smith's voice changed, auditions for a new actor were held, but the crew felt none of them were suitable replacements. As a result, Smith was kept on as the voice of Gerald, whose voice subsequently changed in-universe with the episode ''Gerald's Tonsils''. This would last until [[Hey Arnold!: The Jungle Movie|''The Jungle Movie'']], which featured [[Benjamin Flores Jr.]] as the voice of Gerald instead.

Production of ''Hey Arnold!'' wrapped on December 7, 2001.<ref>{{cite web|url=http://www.dstv.com/Pages/News/731/Nickelodeon's-five-best-animated-shows |title=Nickelodeon's Five Best Animated Shows |first=Tumelo |last=Tladi |date=January 3, 2011 |work=[[DStv]] |publisher=[[MultiChoice]] |access-date=November 25, 2012 |url-status=dead |archive-url=https://web.archive.org/web/20150206212050/http://www.dstv.com/Pages/News/731/Nickelodeon%27s-five-best-animated-shows |archive-date=February 6, 2015 |df=mdy }}</ref> A dispute over a second then-planned ''Hey Arnold!'' movie, ''[[Hey Arnold!: The Jungle Movie|The Jungle Movie]]'', resulted in Bartlett leaving Nickelodeon. The last season's episodes were released over four years, beginning on March 4, 2000. The series aired its final episode, unannounced, on June 8, 2004.<ref name="Nickanimationstudio.com"/> ''The Jungle Movie'' was eventually released as a television film on November 24, 2017.
