Superman Ikuti Alur The Dark Knight Returns Oleh Ruly Riantrisnanto Posted: 11/02/2014 22:20 TOPIK #Batman Vs Superman #Man of Steel 2 #New Release Liputan6.com, Los Angeles : Film bertema Batman Vs Superman (Man of Steel 2) yang menjadi sekuel Man of Steel masih belum menampakkan alur cerita utamanya. Namun sutradara Zack Snyder mengaku bahwa proyeknya itu akan berpegang pada kisah dalam komik The Dark Knight Returns. Kisah dalam The Dark Knight Returns hampir serupa dengan yang disajikan melalui film The Dark Knight Rises pada 2012 lalu. Akan tetapi, suasana kacaunya kota Gotham yang ditawarkan komik karya Frank Miller itu, masih lebih ekstrim ketimbang di dalam filmnya. Zack Snyder juga memuji peran Ben Affleck sebagai Batman yang dianggapnya mampu mengimbangi akting Henry Cavill sebagai Superman. Ben juga dianggapnya sangat cocok memainkan karakter Bruce Wayne yang sudah semakin berumur. Detail cerita film arahan sutradara Zack Snyder dan bekerjasama dengan penulis David S. Goyer itu masih belum diketahui secara lengkap. Akan tetapi, Batman Vs Superman selaku sekuel Man of Steel sudah resmi dijadwalkan untuk tayang pada 6 Mei 2016 mendatang yang mundur dari jadwal semula, 17 Juli 2015.(Rul) 26.
