'Batman v Superman' writer compares film to 'Empire Strikes Back', 'LOTR: Two Towers'Los Angeles, Mar 13(AZINS) Writer of Batman v Superman, Chris Terrio, says Justice League will be on the lighter side.

The Oscar-winning scribe has written the upcoming Dawn of Justice with David Goyer, reported Entertainment Weekly.

"Batman v Superman is a bit of an Empire Strikes Back or Two Towers or any similar middle film in a trilogy. The middle film tends to be the darkest one. I do think from Man of Steel through Justice League, it is one saga really. I expect Justice League will be tonally not quite as dark as Batman v Superman. From that point of view, I felt compelled to go back and try to lift us and myself into a different tonal place because I think when you write a darker film, sometimes you want to redeem it all a bit," Terrio said.

Terrio, who was not willing to take up Justice League initially, said he may not come back for the second part as it has "been the most rigorous intellectual exercise" he has had in his career.
