That's a shot from Francis Lawrence's 2007 apocalyptic zombie flick I Am Legend. The timeline proved to be a little off - Legend is set in 2012, but the Superman/Batman flick won't reach cinemas until sometime in 2015 - but that's still pretty good foreshadowing, don't you think? Even the artwork they revealed is virtually identical.
What do we think of this news, anyway? Rash damage control after audiences proved less enthused about Man of Steel than initially hoped (I very much enjoyed it for whatever that's worth), or genuinely exciting meeting of the brawn ala The Avengers? And was Warner Bros just being cheeky when they inserted this fake billboard easter egg into I Am Legend or was it their sly their plan all along?
