Around 2:30 in you can see their actors/stung guys doing some grappling/submission training in addition to the kung fu/acrobatic stuff they usually do. And to quote Rosie you hear a lot of, "Ching chong ching... MMA... Ching chong... MMA" in the interview. Thank god they don't call it Ultimate Fighting over there.
