Here is Henry Cavill's entire interview fro Studio Cine Live, with thanks to Twitter user @cineloon for the English translation.
Studio Ciné Live: How has Superman evolved since Man of Steel?
Henry Cavill: Superman himself isn’t that different. He does however have to deal with a new set of problems because he’s now been revealed to the world. This film is more about how the world in general – and Batman in particular – sees this alien, and less about the evolution of Superman. We’re seeing Superman and Batman together for the first time in a movie, with flesh-and-blood actors. They’re two sides of the same coin. They have the same goal, but use very different methods to achieve it. Understandably, that leads them to clash with one another, and their conflict is a historic moment.
SCL: How do you plan to portray Clark Kent, the journalist?
HC: Comparisons with Christopher Reeve’s clumsy Clark Kent are inevitable. My Clark Kent is trying to be as small and invisible as possible. If you’re awkward and spilling things constantly, people are going to notice you, and that’s not the best way to go unseen. You have to admit, it’s not a remarkable disguise, just a pair of glasses. He’d like to think that no one will believe he could be Superman. How could such a delicate flower be a living god? Preposterous.
Superman’s suit will evolve from one film to the next, even if they’re just minor updates.
SCL: How is the one featured in Batman v Superman different?
HC: It’s easier to take it off when I have to relieve myself! Suddenly my life is much less complicated.
