How will Justice League fare with fans?

It is viewed as a pivotal film in DC’s long-running battle for supremacy over its fierce competitor, Marvel, which has performed better with its extended universe of inter-related comic book film characters.

Talking Movies’ Tom Brook speaks to Reed Tucker, author of Slugfest, who scrutinised this battle between the two comic book companies.
