Since November 2014, Susannah has been CEO of the Curzon Cinema & Arts in Clevedon, North Somerset, a unique independent cinema, that has run continuously since 1912.

Previously, she was director of Animated Exeter, a lively annual animation festival. In 1996 she founded the Bristol Animation Course at the University of the West of England, supported by Aardman Animations. It was this course along with several years working on and off at Aardman in the camera department that resulted in her first Stop Motion book.

Susannah has also directed radio and television programmes for the BBC, having worked at BBC Bristol as an assistant editor and in the distant past, an assistant animator on the series, Animated Conversations, the BBC's precursor to Channel 4's LipSynch series.
