My interpretation of this is that they're talking about the actual
approach to the kind of story they want to tell -- which is, presumably, a break from what's come before, and is of course still to be determined... But in general approach, using
The Incredible Hulk as an example, you have:
A) The original script, and apparently the original cut, which included bits and pieces of an origin interspersed throughout the film in a "mystery" type narrative (yes, I know this was somewhat done in
Returns).
B) The theatrical version, which incorporated a brief origin during the opening credits -- these sequences were originally intended to be other places in the movie...
And then there's possibilities such as:
C) A completely re-done epic origin film.
D) Perhaps no origin elements whatsoever?
Either way, it's about the approach to the "reintroduction"...
That one's for free...
