Re: Joss Whedon's S.H.I.E.L.D to ABC!
Well, I certainly think it's possible to add X-Men characters to an Avengers (or other Marvel) movie. I just don't think you can add the entire X-Men universe to it and I think adding other Marvel characters to the X-Men universe would weaken that universe. Whedon is adding two X-Men characters to this movie without a problem and he would likely do the same were he to add Wolverine or some other character like that. But it certainly wouldn't be beneficial to add a whole subplot about mutant rights and discrimination to an Avengers movie. In that sense, Mark Webb is correct.
