"Batman V Superman: Dawn of Justice" is surrounded with another set of plot rumours. And this time, it reveals the evil act of Lex Luthor and costume details of Batman, Superman and Wonder Woman.

Going by what the trailers show, we already know that Lex Luthor has got his hands on the kryptonite and General Zod's corpse. But the latest buzz doing the rounds online is that Luthor won't stop with just this. He will kidnap Superman's mom Martha Kent reported Heroic Hollywood.

Umberto Gonzalez wrote: "Remember in "Man Of Steel" how Superman blew General Zod's stack, when his crew went to Smallville to look for the codex on the Kent farm? Superman said, 'You think you can threaten my mother!' A 7-11 & most of downtown Smallville were destroyed in the battle. Only because Zod threatened Martha Kent. So imagine what is going to happen to Lex Luthor for actually kidnapping her?"

Could this be the reason Superman is seen kneeling down before Lex Luthor in the trailer?

Meanwhile, costume designer Michael Wilkinson has revealed costume details of Batman, Superman and Wonder Woman, hinting about hidden script details in those superhero suits.

In her interview with People's Choice Wilkinson said that all the costumes are different from what the audiences have seen before. "I immersed myself in the long histories of these iconic characters — Superman (Henry Cavill), Batman (Ben Affleck), and Wonder Woman (Gal Gadot). I studied how they have been portrayed over the last 75 years on film, on TV, in comic books, graphic novels and video games. I started an exhaustive search for new materials and technologies — original ways of portraying these characters that would be unlike anything audiences have seen before," he said.

Describing details of individual superhero costumes, Wilkinson said, "We tweaked the Superman suit only slightly. We streamlined plus sharpened the details of the costume a little to suit the more earthly (less alien) context of this film. The batsuit is a complete 180 degree turn from the previous film incarnations. The director Zack Snyder wanted him to look as much like the comic book version as possible. As for the Wonder Woman suit, well she has never been seen in a film before, so there was nothing to compare it to."

And finally, the point where we think lies the script details. The designer said, "Zack had a great idea to have some kryptonian script subliminally included in the details of the suit, so we made that happen."

So, the bit about "some kryptonian script" sounds like a teaser. Which character could it be? Is it Wonder Woman?

Well, we will know it when "Batman V Superman: Dawn of Justice" releases on 25 March, 2016.
