Warren Dudley - Director & Producer Sixty 6 Media

“I have worked on two feature projects with James now and hope to work with him many more times in the future. His team is first on my post-production crew list!

His ability to very quickly 'get' what a project needs is a rare ability. He then follows that up with incredible work that is delivered quickly. A directors dream!”
