Re: Bruce's Love Interest?
Bruce does not need a love interest in the film. The time should be allocated to continuing Clark's arc from MOS and introducing Bruce. This a Superman and Batman film, and not Batman and His Amazing Friends Including that Chump Superman.
Justice League (TBD)
Batman: Ben Affleck. Superman: Henry Cavill. Wonder Woman: Gal Gadot. Green Lantern: Tom Anderson.Darkseid: Michael Cera.
Aquaman: Alexander Skarsgard. Martian Manhunter: Liam Neeson. The Flash: Neil Patrick Harris.
