If there is one thing fans know about the "Batman v Superman: Dawn of Justice" trailer, it's that the Joker would be taunting Ben Affleck's Batman by scrawling words in the Robin suit monument in the Batcave.

"HAHAHA Joke's on you Batman," were the words scrawled in bright yellow ink. Many people have began drawing conclusions that Joker must've been responsible for the Boy Wonder's death, and people might get to see the flashback of his death in the 2016 film.

Heroic Hollywood has revealed that the character of Robin might just be played by the son of director Zack Snyder - Eli Snyder. Eli is no newbie in the world of acting. In fact, he was the one who played a young version of Gerard Butler's Leonidas in "300," and he also played young Rorschach in his father's other film "Watchmen."

The buff actor is a six-foot tall Varsity athlete, and many deem him worthy to take on the role of whatever incarnation of Robin "Batman v Superman: Dawn of Justice" decides to go with, be it Dick Grayson or Tim Drake.

Another villain in the upcoming film is Jesse Eisenberg's Lex Luthor, who will stop at nothing to see that his nemesis Superman (played by Henry Cavill) is ruined, humiliated, and destroyed. In fact, it is Luthor who encourages Batman's grudge against Superman, and he even hands the Dark Knight a Kryptonite spear so he can destroy the caped crusader.

However, Cavill said that Superman will not be quick to battle it out with Batman. "Superman wouldn't get into a cage fight with just anyone," he told WWD. "Imagine, you wouldn't get into a fight with someone if they hit you and you didn't feel it, barely registered it. Superman wouldn't even notice; he's not quick to engage." He also told fans not to expect the movie to be a Superman sequel, because it definitely isn't. " This is Batman versus Superman, so it's a separate entity altogether," he explained. "It's definitely an introduction of the Batman character and, ultimately, the introduction of the Justice League films. So yeah, watch the space. See how it turns out."

The script of "Batman v Superman: Dawn of Justice" is written by Chris Terrio and David S. Goyer. Charles Roven and Deborah Snyder are the producers. Aside from Cavill, Affleck, and Eisenberg, other cast members include Amy Adams as Lois Lane, Diane Lane, Laurence Fishburne, Jeremy Irons, Holly Hunter, Jason Momoa as Aquaman and Gal Gadot as Wonder Woman.

"Batman v. Superman: Dawn of Justice" will open March 25, 2016.
