Sam Worthington was considered for the role of Duke, but turned it down due scheduling conflicts with Avatar (2009).
Oh, dude, he would have been SO MUCH BETTER AS DUKE! According to Brian Goldner, the writes took their inspiration mostly from Larry Hama's G.I. Joe comics, and not the animated series. Lorenzo di Bonaventura admits he feels the Cobra Organization, as depicted in the cartoon, was "probably the stupidest evil organization out there!"
It really shows. I loved the little comic shout-outs, like Breaker blowing a bubble, or Hawk in a wheelchair (even if only in four seconds). According to Brendan Fraser, he plays a motorcycle-riding sergeant in the film who is a descendant of Rick O'Connell (also portrayed by Fraser) from Stephen Sommers's The Mummy (1999).
NO. Fraser was Stone or maybe a pre-final-casting/cameo Flint, but THE MOVIE IS NOT TIED TO THE MUMMY MOVIES YOU BASTARDS. I don't care what people like "the director" say... Byung-hun Lee, who plays Storm Shadow, had no knowledge of the G.I. Joe saga, but was advised by the filmmakers not to learn about his character, letting his portrayal stand by itself. He describes Storm Shadow as defined and driven by two conflicting facets: "huge pride and a sense of honour."
Gotta be honest, I thought he came off as pure douchebag. Lee would have done well to read the Storm Shadow stories in the comics, because they might have given him a sense of the character's potential for complexity, even when he's a Cobra assassin.
Anyway, when the movie started, and the screen said, "In the not too distant future...," did anyone else sing/shout out, "Next Sunday, A.D.!"?
