“Justice League” production is in trouble if you believe Batman On Film, which has been a realiable source in the past, they had this to say about the probems:
"I have been told by a 100% vetted and more-than-reliable source that re-shoots on JUSTICE LEAGUE have commenced in London under the helm of Joss Whedon and that they will be “significant.” So much so, that these reshoots are expected to take place through June and July, and maybe into August. They are NOT your “standard” pick-ups. Also, my source tells me that despite how this might look, he’s pretty optimistic that these re-shoots (though, I don’t know if that’s the correct noun – “additional photography” is probably more appropriate) are a positive in terms of making the best film possible."
