Oh, Dan does ALL sorts of things--allow me to gush for a moment:
He choreographs, rigs, and performs stunts--EVERYTHING you saw Eric do was actually Dan--he didn't need a stuntman. He's had extensive training as a gymnast, acrobat, and martial artist so very little is beyond him. He continues to do mo cap (motion capture) and voice-over work for many, many video games (he was Vergil in Devil May Cry 3) and tv shows/films.
As he's talked about in several interviews, he played multiple Rangers in the touring Power Ranger Stuntshow and he worked on the TV show as a stuntman before he secured the part of Eric in Time Force.
If you have any specific questions about his work, please let me know!
