Justice League was due to be shot at Fox Studios this year until Warner Bros suspended production last month, citing uncertainty over the new incentives. Based on a comic book, it is due to star the Australians Megan Gale, Teresa Palmer and Hugh Keays-Byrne among eight lead roles and employ a huge crew that includes visual effects specialists.
"One of the reasons for doing Justice League in this country is the opportunity to bring back all the people we lost on Happy Feet who went overseas," Miller said. "We spent four years developing this talent and the cream of them left because they didn't have another film to go on to ...
"The idea is to say come back, start off on Justice League then move onto Happy Feet 2."
Miller described the movie's status as "precarious" and said Warner Bros was pushing for it to be shot overseas, with Canada the most likely option.
