"In 2006, Marvel launched a new ongoing series, The Immortal Iron Fist, co-written by Ed Brubaker and Matt Fraction and featuring art by Spanish illustrator David Aja. "The Immortal Iron Fist" began with a six-part arc, counter-intuitively titled "The Last Iron Fist Story". The story reveals the Iron Fist to be a legacy power conferred on the champion of K'un Lun roughly once a generation. There have been sixty-six Iron Fists. K'un L'un is also revealed as one of the Seven Cities of Heaven, each of which has an analogous champion Warrior.
"The story introduces Orson Randall, Daniel Rand's immediate predecessor, who reneged on his responsibilities to K'un L'un after suffering immense psychological trauma during the First World War. Randall is discovered in Thailand; apparently preserved by the spirit of Shou-Lao and in full possession of his powers, but living in drug-soaked seclusion. Randall is pursued by agents of the Steel Serpent and the terrorist group HYDRA. Jolted out of his decades-long ennui, Randall seeks out Daniel Rand in New York and gives him The Book of the Iron Fist, a sacred ledger supposedly containing all the Kung-fu secrets of previous Iron Fists, which Randall claims will be necessary if Rand is to compete successfully in the coming tournament of the Seven Champions."

Now the cast you've all been waiting for...

The Father who sacrifices himself for his family... I decided to bring back an old veteran since he's not really in the story anyways.
I'm going to follow JOSHW on this besides Mom dies immediately too...
Now Harold was a bad guy until karma thought him a lesson and since he's a recurring role I decided to spend some fictional money and cast a name that will attract tons of non-comic fans...
JOSHW was spot on for both of these characters but watch how things change up...
I like to cast my heroes young so they can last a couple sequels... Sean Faris can clearly fight. We saw that in "Never Back Down". I know he's not blonde but how easy is that to fix? Hair Color and stop shaving for a couple days, He'll look just like Daniel and he'll do amazing...
What's a man without a woman by his side?
Meaghan good already got the attitude, already got the looks and already got the part...
A man gotta have backup...
Got the looks, got the size, doesn't need to fake ghetto. I'm really annoyed of people overusing Terry Crews... I mean can he even play a serious role?
We all know her well... Sin City is all you need on a resume not to mention she looks exactly like in the comics.
So Jason Statham makes a better Taskmaster. Bruce Willis makes a perfect Orson. All things that work together...
A hero ain't a hero if he ain't got enemies...
Never seen him fight but I kinda used all most of my other options in my DC vs Mortal Kombat cast lol.
If you ain't convinced, watch "Blood and Bone"
And that's it folks.Talk it up...
