While you might think everything that could be said about Elvis has been written or filmed, the version of his story told by his half brother David, who ended up as his bodyguard, is told in the film Protecting The King
There is a lot of insight into the bodyguard bit of The King's later life, a lot of which has been told by his other bodyguards such as Red West, and there is some interesting back story regarding his training in Kenpo under Ed Parker
In this scene, Larry Tatum plays Mr Parker (and yes, he could have taken the tash off to look more authentic for the film) so we get to see some good, albeit over the top, American (version of) Kenpo

also if you watch to the end the technique David does on his partner is Thundering Hammers - although the backfist at the end is misplaced (and he doesn't get to do the moosky)
