News of Batman v Superman: Dawn of Justice's first teaser getting leaked online surfaced last month, and now the 'alleged' clip, that was published on YouTube a couple of days back, seems to have gone viral. Check it out below:

While this clearly is a fan-made version, rumours suggest that the film's first clip will feature Batman listening to Zod's "You're Not Alone" recording.

The film's teaser is rumoured to be revealed at the 2014 San Diego Comic Con next week.

One has to admit that featuring Batman in the eagerly-awaited film's first clip ever, is definitely the way to go.

Meanwhile, Gary Oldman, who starred as Commissioner Gordon in Christopher Nolan's The Dark Knight trilogy, has revealed his thoughts on the upcoming Batman v Superman: Dawn of Justice, and he does not seem particularly sold on the idea just yet, reports EnStars.

"They want to keep it going. Of course they do. But, it's Superman yeah? Batman and Superman together? We shall see," Oldman said during a press conference for his latest movie, Dawn of the Planet of the Apes.

"The thing about Nolan, there was some grounding of reality to it. In our trilogy, and as fantastical and as big as The Joker was, it was based [on reality]... we could relate to it."

He explained that bringing Batman together with "a guy who can fly, who's an alien" made him a bit skeptical that it could work.

"It's got big shoes to fill," he stated.

Batman v Superman: Dawn of Justice is not scheduled for release in cinemas until May 2016.
