will Ben Affleck also play Batman in the justice league movies?

[TJanssen411]

so far as I understand it Yes, Bat-Fleck will be the Bat of the proposed JL Universe if the films take off like Marvel's Avenger-verse

this is part of why they likely went with Affleck... who is more notable for his supporting work AND his Directorial work than he is for his lead roles... Odds are Batman will be in most of the projects But will be a supporting character... and at some point Affleck will be given the director's chair for either the actual Justice League titles or one sub-franchise

just because the 'hashtag' seems to be Batman Vs superman there is no reason to assume or even expect that the Plot will actually involve them coming to Blows for more than an introductory Scene
-- Snyder may be citing 'Dark Knight Returns' in interviews but honestly having watched the recent animated adaptation there is no logical way to Remake that story as a Superman movie... Not to mention the lack of other established heroes in the world of Man of Steel removes a Key Plot point from the back story of 'Returns'
