In an interview Patrick Halm describes his films as following.
My films are non-narrative. Poetry, modern symphonic music and the rich varied history of the cinema influence my work. I have a fascination with film's ability to emulate the subconscious thought process. By layering image and sound fragments over each other physically and temporally I create a charged span of time. I am interested in creating films where the present does not devour the past and the future, but rather expands the present moment to give a sense of the whole time line as one thought. Above all, my films create a space where viewers can exercise their imagination and form their own conclusions.

Patrick Halm has worked several times with the artist Marie Rafalko.
