The insiders at IESB.net have heard lots of interesting things about the 'Justice League' movie.
Their sources tell them that the rumored move to Canada seems likely, at least to some sources close to the production. Fans recall that issues with the Australian tax have made Warner less eager to film on another continent.
What about talk that Batman and Superman are being written out of the script? "Total bullshit," and unknown source is quoted as saying. The rewrites being done are supposedly to punch up the third act.
