Povenmire was born in San Diego, California on September 18, 1963, and grew up in the city of Mobile, Alabama. A child prodigy, he began drawing at age two; by the time he was ten, his work was displayed in local art shows. His first efforts in animation included a series of flip books that he produced in his school text books. As a child, Povenmire considered animator Chuck Jones his hero; in a 2009 interview, he stated that "every drawing he [Jones] did was beautiful to look at and had so much energy in it".
Povenmire later became a director on Family Guy, starting with the season two episode, "Road to Rhode Island". Creator Seth MacFarlane granted Povenmire substantial creative freedom. Povenmire recalled that MacFarlane would tell him "We've got two minutes to fill. Give me some visual gags. Do whatever you want. I trust you." Povenmire praised MacFarlane's management style for letting him "have [...] fun." Povenmire brought realism and material from his own experiences to the visual direction of Family Guy. For "One if By Clam, Two if By Sea" (August 1, 2001), several characters demonstrate Fosse-like moves in prison. To correctly depict the moves, Povenmire asked color artist Cynthia MacIntosh, who had been a professional dancer, to strike poses so he could properly illustrate the sequence. In the episode "To Love and Die in Dixie" (November 15, 2001), Povenmire drew on his childhood in the Deep South to create and sequence a background scene in which the redneck character nonchalantly kicks a corpse into the nearby river. "Brian Wallows and Peter's Swallows" (January 17, 2002), a Family Guy episode which Povenmire directed, won the Emmy Award for Best Song. Creator MacFarlane, the recipient of the award, noted that Povenmire deserved to have received the award for the contribution the visuals made to the episode's win. Povenmire jokingly responded "That's a nice sentiment and all, but did he offer to give me his? No! And it's not like he doesn't already have two of his own just sitting in his house!" Povenmire was nominated for an Annie Award for Directing in an Animated Television Production for the episode "PTV" (November 6, 2005) but lost out to a fellow Family Guy director Peter Shin, who had directed the episode "North by North Quahog". Povenmire and several others were also nominated for their work on "PTV" in the Outstanding Animated Program (for Programming Less Than One Hour) category at the Primetime Emmy Awards. Povenmire also received the same nomination for "Road to Rhode Island." During Family Guy's brief cancellation, Povenmire was offered a job as storyboard director of the series SpongeBob SquarePants. He wrote various musical numbers for the series, including "The Campfire Song Song" in "The Camping Episode" (April 3, 2004).

Did he write the storyline for Family Guy?

"Trapped in the Closet" is the twelfth episode in the ninth season of the American animated television series South Park. The 137th episode of the series overall, it originally aired on Comedy Central in the United States on November 16, 2005. In the episode, Stan joins Scientology in an attempt to find something "fun and free". After the discovery of his surprisingly high "thetan levels", he is recognized as the reincarnation of L. Ron Hubbard, the founder of the church.
Saving for a bicycle and not wanting to spend money on entertainment, Stan takes a free "personality test" being offered by Scientologists on the street. After answering a long questionnaire, Stan is informed that he is extremely depressed and therefore a perfect candidate for Scientology. They offer to help him out for $240. Back home, Stan asks his parents for the money. His father suggests that he use the money he had been saving. Stan pays and is taken into an auditing room where an attendant reads his "thetan levels" using an "E-meter". Stan has such a high reading that the Scientology headquarters in Los Angeles is notified. There, the president of Scientology determines that, because his reading is so high, Stan must be a reincarnation of L. Ron Hubbard, Scientology's founder and prophet. Later that night, a large group of Scientologists, including John Travolta, gather outside the Marsh house to celebrate Hubbard's "second coming". The president of Scientology arrives in a helicopter and talks with Stan's parents. They are opposed to Stan's participation, but the president informs them that "we're not asking him to join us; we're asking him to lead us". Randy sends Stan to his room, where he finds Tom Cruise waiting. Cruise, believing that Stan is genuinely Hubbard's reincarnation, asks him whether he has enjoyed his acting. When "Hubbard" replies that his acting is okay but not as good as others' such as Leonardo DiCaprio or the Napoleon Dynamite guy, Tom hears that he is "a failure in the eyes of the prophet" and locks himself in Stan's closet. He refuses to come out, despite the entreaties of Randy, Nicole Kidman, the police, Travolta and R. Kelly to "come out of the closet". Travolta and Kelly eventually join Cruise in the closet. Downstairs, the church president tries to convince Stan's parents to allow their son to participate. He tells to Stan the great secret behind the church -- a condensed version of the story of Xenu, based directly on the Scientology Operating Thetan III document, and accompanied by an onscreen caption reading "This is what Scientologists actually believe". He then begs Stan to continue writing where "L. Ron" left off. Stan, impressed by the story, does so. He shows his writings to the Scientology president, who initially approves of the work, but when Stan says "to really be a church, you can't charge money to help", the president reveals to Stan that the church is in reality a global money-making scam. He asks that Stan continue with that in mind. Stan appears to agree and keeps writing. Outside the house, the president introduces Stan to his followers, to whom he will read parts of his new doctrine. However, instead of presenting it to them, Stan states that he is not the reincarnation of L. Ron Hubbard, and that "Scientology is just a big fat global scam". The Scientologists grow angry and threaten to sue him. The celebrities in the closet appear, threatening to sue Stan as well. The last shot is Stan daring them to do so. However, that shot is followed immediately by the closing credits naming only "John Smith" and "Jane Smith", a reference to Tom Cruise and the Church of Scientology's reputation for litigiousness.
