So if you've been following the Avatar 2 rumours you may have heard that there is a rumour going around saying that casting orders appear to be changing and Stephen Lang's Quaritch may become the focus of the film.

Do people think this is a good development or not?

I'm casting my vote for not.

These are rumours just like the ones about 1D or Justin Bieber or any celebrity. A rumour comes from no official statement (or a misinterpretation). Odds are it's not true, so you can relax.

Otherwise, to answer your question, I would say no. It would require a very developed thinking to find any constructive manner to develop the story with this and this way perpertuate the message. It's the antagonist of the story, just saying.

Where have you been getting these rumors from?

Whatever source it is, the accuracy of a rumour is questionable. I searched Quaritch on Google News and I got websites like Christian Times and Movie News Guide and Vine Report. I must conclude that since these are not popular websites that have made their name in terms of credibility, I can disregard the rumour.

If JC or John Landou doesn't originate it, then I wouldn't get too excited or upset about any rumor
