In 1997, Kitamura directed and produced the short film Down to Hell, which received a positive response from students, teachers, and an award which motivated Kitamura to seriously pursue a film career. He went on to independently finance and direct his feature film debut Versus (2000). The film proved to be successful within the film festival circuit and opened doors for Kitamura to direct more high-profile films such as Alive (2002), Sky High (2003), Godzilla: Final Wars (2004), The Midnight Meat Train (2008), No One Lives (2012), the live-action adaptation of Lupin the 3rd (2014), and several other Japanese and Hollywood productions.
