Directing
After losing interest in acting, Kent was inspired after seeing Dancer in the Dark to pursue a career as a filmmaker. She wrote to the director Lars von Trier, asking to study under him and explaining that she found the idea of film school repellent. In 2002 von Trier allowed her to assist him as part of a directing attachment on the set of his film Dogville (2003) starring Nicole Kidman. In a journal by Paul Risker, which speaks about "The Quarterly Review of Film & Video", Kent shared her journey on becoming a director. While working with Lars von Trier, she "learned a lot about directing watching him at work." In 2006 Kent directed an episode of Two Twisted, an Australian series following in the tradition of The Twilight Zone.
In 2005 Kent directed her short film Monster, which was screened at over 50 festivals around the world, including Telluride, Montreal World, and Slamdance film festivals, SXSW, and Aspen Shortsfest.
While she didn't make this short film with the idea of The Babadook already in mind, she says people think otherwise. She claims that without this short film, The Babadook wouldn't have been possible. Before making The Babadook, Kent made three to four full-length feature scripts that couldn't get funded within Australia. She was left with two choices: give up or go outside of Australia. She states that Binger, a film lab in Amsterdam that acts as a creative residence for writers and directors, helped support Kent through the creation of The Babadook and, ultimately, saved her creative life. In 2014 she adapted her short into a feature-length film The Babadook starring Essie Davis whom Kent had known through drama school. The film tells the story of a single mother played by Davis who must confront a sinister presence in her home while dealing with the emotional fallout of her husband's death. Kent explains "[she] was always quite fascinated by people who could suppress really dark, deep, painful experiences and [she] wanted to explore the idea that perhaps pushing down on those terrible experiences is harder than facing them". The Babadook premiered at the 2014 Sundance Film Festival, and was quickly picked up for distribution in the U.S. by IFC Films. Kent did five drafts of the feature script, received most of her funding from the South Australian Film Corporation, then conducted a Kickstarter campaign to help raise US$30,000 to pay for set construction. The Babadook received widespread critical acclaim, and doubled its budget with $4.9 million in the worldwide box office. The Babadook script won the Betty Roland Prize for Scriptwriting at the 2015 New South Wales Premier's Literary Awards.
Kent has been vocal in the press about the lack of female directors in horror cinema. "It will shift, as the world shifts. Women do love watching scary films. It's been proven, and they've done all the tests. The demographics are half men, and half women. And we know fear. It's not like we can't explore the subject."
Kent met with executives at Warner Bros. in late 2014 to talk about possibly directing the Wonder Woman film, a job which eventually went to Patty Jenkins.
Later in March 2017, Jennifer Kent began the production of The Nightingale, starring Aisling Franciosi and Baykali Ganambarr, who play Clare Carroll and Billy. The film takes place in 1825 and tells a story of Clare, who seeks vengeance, and a tracker named Billy, whom she hires.
While making the film, Kent felt that she couldn't authentically tell the story unless she collaborated with Tasmanian Aboriginal people. While in Tasmania, she eventually got in touch with Jim Everett, who became a part of the film's production. In an interview called "Once Upon a Time in Van Diemen's Land" by Graham Fuller, Kent shared, "We enlisted 'Uncle' Jim Everett, a Tasmanian Aboriginal Elder, who could speak directly to the experience." She also states that without Jim Everett's vast input, she wouldn't have made Billy as real as possible. She also stated that Nightingale "was the only movie directed by a woman to play in competition at the Venice Film Festival last year."
