In 1998, Yuh joined DreamWorks Animation as a storyboard Artist, while her sister, Catherine Yuh Rader, also a storyboard Artist, had joined DWA owned PDI. Jennifer worked then on Spirit: Stallion of the Cimarron, Sinbad: Legend of the Seven Seas and Madagascar. As a big fan of martial arts movies, she asked to work on the first Kung Fu Panda film, where she was a head of story, and directed the hand-drawn dream sequence. After the release of Kung Fu Panda, Jeffrey Katzenberg, DWA's CEO, approached Yuh about directing Kung Fu Panda 2. Although she hadn't expressed interest in directing the sequel to the film, Producer Melissa Cobb stated that she should direct the second one due to her excellent work on the first, to which the rest of the crew supported the decision. The film proved a major critical and international box office success with a worldwide gross of $665.6 million, making it the highest-grossing film ever directed by a woman, until Director Jennifer Lee's Frozen two years later. She held the record for highest-grossing film by a solo female Director until the release of Patty Jenkins's 2017 film Wonder Woman. She eventually became the first woman to be nominated for the Academy Award for Best Animated Feature Film (since 2007's Persepolis) and to win the Annie Award for Best Directing in a Feature Production. Jennifer returned for Kung Fu Panda 3, which was released in 2016 and was the first American animated film to ever been co-produced with a Chinese firm. In July 2016, she was also added as one of the board of Governors by Academy of Motion Picture Arts and Sciences.
