This site says that they offered the role of Shipwreck to the Rock, but no dice.

My two favorite characters Snake Eyes and Storm Shadow have a mentor...

...In other Joe movie news, Gerald Okamura has been cast as the Hard Master in the upcoming film.  The Hard Master is the ninja master/leader of the Arashikage clan who mentors both Storm Shadow and Snake Eyes in the ways of the ninja.  Hard core Joe comic fans know that the Hard Master has something to do with the long standing rivalry between Snake Eyes and Storm Shadow...

Every asian kid loved snake eyes and storm shadow.

I was no exception to this rule.

i agree Al.

Storm Shadow >>> Snake Eyes

though 

Man, I love Storm Shadow and Snake Eyes equally.

Other favs:

Zartan And The Dreadknocks

Dusty

Cobra Commader (with his hood on)

Tomax  & Xamot

Beach Head 

Flint 

Roadblock 

Gung Ho 

Dude, snake eyes was a blind ninja that could still kick asses... plus he wore black.

Sorry Daba... Snake Eyes > Storm Shadow.

Banger wasnt Gung Ho mildly retarded? ... or am I thinking of Hacksaw Jim Duggan.

I didn't like Snake Eyes costume it was all futuristic robot-like. Storm Shadow had a sweet traditional ninja costume.
