Full Service Post Production Company
MAD LOON
Welcome to Mad Loon! Specialized in post-production, we aim to be a one stop shop like all the big post houses, but we're indie filmmakers too.
Our team provides editing, coloring, composing, sound design, and sound mixing. With a wide range of experience, we deliver a high-quality studio finish with a lean crew to work with smaller budgets.
THE TEAM
