Deborah Mason was born in London and trained in acting at the School of the Science of Acting. The school focuses on Stanislavski based acting techniques. However future theatre work took Deborah in the direction of physical theatre, performance art and devised works, as well as writing performing works with literature links. Film work has been equally 'interesting' and her middle-class, middling, middle height appearance is often used by directors as a foil for crazy, psycho, surreal characters.
