Hannah Marshall was born in Auckland, New Zealand and embarked on an acting career after a successful stint as a gymnast, having represented New Zealand in the sport from ages 10 to 14, including a Junior World Championship appearance in Colorado, where a back injury forced her to stop competing.
She transitioned to acting, starting on stage, starring in Milo's Wake, which enjoyed two sold-out seasons and toured New Zealand. Marshall then began devising theatre work with Fingerprints & Teeth and landed a lead role in her first TV show, Amazing Extraordinary Friends. She continued to work in television and film, appearing in several acclaimed New Zealand shows while pursuing her BA in English.
In 2009, Marshall relocated to Australia, where she secured a series regular role in the country's number one drama, Packed to the Rafters, a position she held for four years.
After starring in the critically acclaimed indie film The Infinite Man, which premiered at SXSW, Marshall moved to Los Angeles. While in LA, she worked on several TV shows, studied under renowned acting coach Nancy Banks, and wrote her first feature script, Girl One, as well as the online series Alibi.
Marshall later relocated to New Zealand to produce and direct Alibi, an award-winning, non-linear crime drama, which she also wrote. She was nominated for a New Zealand Television Award for Best Writer for her work on Alibi in 2019, alongside writing partner David de Lautour.
Marshall recently finished filming her first short film, Frankie Jean & the Morning Star, which she wrote and directed. She has also penned the pilot script of Alibi with David de Lautour and showrunner Craig O'Neill for CBS Network, in collaboration with JBTV and CBS Studios in the US.
Currently, Marshall splits her time between the US and New Zealand (via Australia),creating, directing, and producing television and feature film content with her company Plus6Four, while continuing her acting career.
