Dan actually worked with Jackie Chan and the Alpha Stunts team. He did some work on the set of PR as a stunt man before ever becoming a Ranger.
Also, he played several Rangers when they did the live appearances at various malls and other venues where the Rangers never removed their helmets.
Dan has a fan run, approved by him Facebook page.
