There's no regret. You can't regret. I mean I've felt regret but I've also refused to allow regret to sow a seed and live in me because I don't believe it. You feel it it's like guilt it's like jealousy it's like all those horrible things. You've just got to snip them and get them out because they're no good.
What people adore about superhero movies is the signal quality of the Christopher Nolan films - their complete lack of irony when it comes to the portrayal of heroism and the need for heroes to confront evil.
