There is something amazing about seeing actors don superhero costumes. Even Wonder Woman star Gal Gadot herself was awestruck when she first wore her costume alongside "Batman v Superman: Dawn of Justice" co-stars Ben Affleck and Henry Cavill.

"It was crazy!" Gadot enthusiastically told Total Film. "You don't do fittings together. You do them separately. But the first time they shot the trio, it was almost magical. On the one hand, when you think about it realistically, it's kind of weird to stand there, all three of us dressed as superheroes. And then, when we started to shoot, Ben became Batman, Henry became Superman, and I became Wonder Woman. I can't even express in words how excited I was."

Even director Zack Snyder felt floored when he saw the three of them in action.

"There was actually a moment in the costume test where there was Batman, Superman, and we were testing the Wonder Woman costume at the same time," Snyder recalled. "They were all standing there. I was like, 'Oh my, this is crazy.' It's crazy enough just to see the two of those guys together. Once you see the Trinity..."

Aside from the stars mentioned, other actors included in the film are Amy Adams as Lois Lane, Jason Momoa as Aquaman, and Jesse Eisenberg as Lex Luthor.

Snyder earlier said that "Batman v Superman: Dawn of Justice" is somewhat like "Man of Steel 2," and this is why he feels the need to deliver a compelling storyline.

"The pressure's on us, the filmmakers, to make the movies better. It's about human stories; it's not just about big explosions and stuff. What are these people feeling?" Snyder told Canoe during an interview. "Where you end up in the genre, where you end up in our thing, is on your shoulders. What I'm trying to do is guide the talent toward a real foot in the door."

One of the main goals of the film is to introduce and bring together the Justice League, and Snyder hopes to achieve that as well.

"Justice League is kind of the transcendent, knights-of-the-round-table of the story. It'd be interesting to think about what a standalone Superman movie might be," he said. "We really have to figure out the why of them. And I think that we have. That's the one thing that's cool to me about 'Batman v Superman,' it's all about the mythology of these two massive icons. And I think that's compelling."

"Batman v Superman: Dawn of Justice" will be released on March 25, 2016.
