Superhero movies are a big trend right now, with Hollywood jumping on from one blockbuster to the next. Marvel and Warner Bros. are both banking heavily on this trend, with a slate of superhero movies lined up with both studios. So with Fantastic Four, Avengers, and Batman v. Superman movies on the way (and many more in the works!), will people's desire to watch caped crusaders wane in the future?

According to Warner Bros. chairman-CEO Kevin Tsujihara, this is not the case. He said in an interview with Variety that there is no superhero fatigue since both studios have different takes on their films.

"The key thing is that the movies and the television shows and the games, everything looks very different ...you have to be able to take advantage of the diversity of these characters," said Tsujihara.

He added that Warner Bros.' releases are "edgier" than that of Marvel's.

"The worlds of DC are very different," he said. "They're steeped in realism, and they're a little bit edgier than Marvel's movies."

Tsujihara believes in this so much so that they will be releasing Batman v Superman: Dawn of Justice and Suicide Squad in 2016, and they have The Flash, Aquaman, and Shazam in the works.

"The big franchises are becoming more and more valuable," said Tsujihara. "You don't have to explain to the consumer what a 'Batman v Superman' is."

The idea to connect all the superheroes to team up and cross over one film to another actually came from Marvel (hello, Avengers!), and Warner Bros. responded to this phenomenon with the Justice League. But Tsujihara said that DC characters such as Batman and Superman are way different than Iron Man, Spider-Man and Captain America.

Another positive thing about comic book movies is that the film business has become increasingly global, with 70 percent of box office earnings of major films coming from abroad. And because characters such as Superman have reached China, Russia, and different parts of the world, it is now easier for studios to promote and campaign any upcoming movies about them.

The only thing that concerns Tsujihara about Warner Bros. is a possible cyber-security attack, the same that happened to Sony. The company is currently trying to overcome any threats, but Tsujihara cannot assure that hackers won't breach in to their security.

"We're seeing more attempts to get into our system than ever before," he admitted.
