Astrophysicist and StarTalk host Neil deGrasse Tyson provide one of many celebrity voices that can be heard in the first Batman v Superman trailer. That is why The Daily Show host Jon Stewart asked Tyson to explain to him how a battle between the two heroes comes about.
Neil deGrasse Tyson: Who does Batman (Ben Affleck) report to?
Jon Stewart: Commissioner Gordon.
Neil deGrasse Tyson: Yeah, the Commissioner and ultimately, the Mayor.
Jon Stewart: Yeah.
Neil deGrasse Tyson: Who does Superman (Henry Cavill) report to?
Jon Stewart: The guy in the ice castle.
Neil deGrasse Tyson: Yeah, so nobody we know. Nobody we have any insight into. He just behaves in any way he wants. And so at the end of the day, what might matter is the public reception of the superhero's conduct. And if Batman executes our wishes in the city, and Superman does whatever the hell he wants: that's a conflict.
