Stephen McDannell Hillenburg (born August 21, 1961) is an American cartoonist, animator, writer, producer, director, and former marine biologist. He is the creator of the Nickelodeon television series SpongeBob SquarePants (1999-present) which he has also directed, produced, and written. It has gone on to become one of the longest-running American television series as well as the highest-rated show ever to air on Nickelodeon. Born in Lawton, Oklahoma and raised in Anaheim, California, Hillenburg became fascinated with the ocean as a child and also developed an interest in art.
After graduating from college, Hillenburg held various jobs in 1984, including as a park service attendant in Utah and an art director in San Francisco, before landing the job he wanted: teaching children. He hoped to work in a national park on the coast, and eventually found a job at the Orange County Marine Institute (now known as the Ocean Institute), an organization in Dana Point, California that is dedicated to educating the public about marine science and maritime history. Hillenburg was a marine-biology teacher there for three years: "We taught tide-pool ecology, nautical history, diversity and adaptation. Working there, I saw how enamored kids are with undersea life, especially with tide-pool creatures." He stayed at the Dana Point Marina and was also a staff artist. Although "[i]t was a great experience" for him, during this period, Hillenburg realized he was more interested in art than his chosen profession. While working there, he was asked by one of the educational directors if he would be interested in creating an educational comic book about the animal life of tidal pools. He created a comic called The Intertidal Zone, which he used to teach his students. It featured anthropomorphic forms of sea life, many of which would evolve into SpongeBob SquarePants characters--including "Bob the Sponge", the comic's co-host, who resembled an actual sea sponge, as opposed to his later SpongeBob SquarePants character, who resembles a kitchen sponge. He tried to get the comic published, but was turned down by the publishers that he approached. At one point during his tenure with the Orange County Marine Institute, Hillenburg started going to animation festivals such as the International Tournee of Animation and Spike and Mike's Festival of Animation where, at one of those, films made by California Institute of the Arts (colloquially called CalArts) students were shown. He determined that he wanted to pursue a career in that field. Hillenburg had planned to take a master's degree in art, but instead of "going back to school for painting", he left his job in 1987 to become an animator. In 1989, Hillenburg enrolled in the Experimental Animation Program at CalArts. About this decision, he said: "Changing careers like that is scary, but the irony is that animation is a pretty healthy career right now and science education is more of a struggle." He studied under Jules Engel, the founding director of the program, whom he considers his "Art Dad" and mentor. Engel accepted him into the program impressed by The Intertidal Zone. Hillenburg said, "[Engel] also was a painter, so I think he saw my paintings and could easily say, 'Oh, this guy could fit in to this program.' I don't have any [prior experience in] animation really." Hillenburg graduated in 1992, earning a Master of Fine Arts in experimental animation.

What did he start his career in?

park service attendant in Utah and an art director in San Francisco, before landing the job he wanted: teaching children.

Dreamgirls is a 2006 American romantic musical drama film written and directed by Bill Condon and jointly produced and released by DreamWorks Pictures and Paramount Pictures. Adapted from the 1981 Broadway musical of the same name by composer Henry Krieger and lyricist/librettist Tom Eyen, Dreamgirls is a film a clef, a work of fiction taking strong inspiration from the history of the Motown record label and one of its acts, The Supremes. The story follows the history and evolution of American R&B music during the 1960s and 1970s through the eyes of a Detroit, Michigan girl group known as the Dreams and their manipulative record executive. The film adaptation of Dreamgirls stars Jamie Foxx, Beyonce, Eddie Murphy, and Jennifer Hudson, and also features Danny Glover, Anika Noni Rose and Keith Robinson.
Dreamgirls premiered on December 4, 2006 at the Ziegfeld Theatre in New York City, where it received a standing ovation. The film's Los Angeles premiere was held on December 11 at the Wilshire Theater in Beverly Hills. Similar to the releases of older Hollywood musicals such as The Sound of Music, My Fair Lady, and West Side Story, Dreamgirls debuted with three special ten-day roadshow engagements beginning on December 15, 2006 at the Ziegfeld Theatre in New York City, the Cinerama Dome in Los Angeles, and the AMC Metreon 15 in San Francisco. Tickets for the reserved seats were $25 each; the premium price included a forty-eight page full-color program and a limited-print lithograph. This release made Dreamgirls the first American feature film to have a roadshow release since Man of La Mancha in 1972. Dreamgirls earned a total of $851,664 from the roadshow engagements, playing to sold-out houses on the weekends. The film's national release, at regular prices, began on December 25. Outside of the U.S., Dreamgirls opened in Australia on January 18, and in the United Kingdom on February 2. Releases in other countries began on various dates between January and early March. Dreamgirls eventually grossed $103 million in North America, and almost $155 million worldwide. DreamWorks Home Entertainment released Dreamgirls to home video on May 1, 2007 in DVD, HD DVD, and Blu-ray formats. The DVD version was issued in two editions: a one-disc standard version and a two-disc "Showstopper Edition". The two-disc version also included a feature-length production documentary, production featurettes, screen tests, animatics, and other previsualization materials and artwork. Both DVD versions featured alternate and extended versions of the musical numbers from the film as extras, including the "Effie, Sing My Song" scene deleted during previews. Both the Blu-ray and HD DVD versions were issued in two-disc formats. Dreamgirls was the first DreamWorks film to be issued in a high definition home entertainment format. As of 2017, total domestic video sales to date are at $95.1 million. A "Director's Extended Edition" of Dreamgirls was released on Blu-Ray and Digital HD on October 10, 2017 by Paramount Home Media Distribution. This version, based on edits done for preview screenings before the film's release, runs ten minutes longer than the theatrical version and features longer musical numbers (including songs and verses cut during previews) and additional scenes.
