I understand what you're getting at, but I mean, come on; how much technique is there going to be before you're just watching MMA? People who haven't trained aren't going to know what's going on, so they're not going to appreciate the intricasies of a perfectly timed Matador guard pass to knee mount, where the top man waits ever-so-patiently for the right hand placement before going for an armbar. The majority of an audience for a movie is just going to appreciate seeing people get hit, and maybe once in a while a limb broken or choked out. Weapons also usually come into play.
If you're going to apply to the MMA audience, here's what you do: put together an MMA event. Otherwise, you're going to have to settle for some small elements of MMA in a movie which focuses more on a solid plotline.
Besides, have you ever shown the untrained eye a BJJ or Sambo match? People who haven't seen or experienced what these arts can do think it looks like sex. Plain and simple. What if, say, just for a minute, there was another completely NHB rules fight; anything goes, and some mystical style that defied the laws of aliveness and everything we thought we knew about fighting came from some unexpected country, like the United Arab Emirates, and it totally destroyed MMA and all single styles? But, what if this art was based around a position where two fighters are liplocked? Those of us who are used to MMA would think "Oh God, he's kissing him! Gross!" But to these martial artists, they've somehow found a way to beat up people with their lips.
Obviously, it's a ridiculously hypothetical idea. Please don't think I'm saying the above is even possible. But now, I've shown my point, in that people who haven't watched MMA or aren't martial arts enthusiasts think the ground positions look erotic, and for good reason: the only time they're in positions like that is, well, when they're having sex. People aren't used to moving on the ground, let alone fighting on it.
Long post but I had to get some thoughts out. I'm sick and bored out of my skull because I can't train in any way.
