I'm Batman! Ben Affleck made his first appearance on the set of Suicide Squad, but was kept under wraps

Despite covering the actor in a giant black sheet, the outline of the crimefighter's bat-ears were unmistakable, while his signature black rubber boots were a dead giveaway too.

Ironically on the same day, the clearest image yet of Affleck as Batman surfaced online.

Despite being announced as the new Caped Crusader two years ago, very few images of Affleck as Batman have been released; the few that have are very dark or obscure.

The most recent popart-esque promotional posters for Batman V Superman: Dawn Of Justice show the rivals, each with their faces obscured by the other's insignia.

But on Thursday internet forums lit up when what appeared to be the original photo surcaed online, showing the clearest image yet of the 42-year-old in the iconic cowl.

Although the image could very easily be fake and extrapolated from existing images, most fans online agree it is the real deal.

On Tuesday fans reacted excitedly when photos emerged of Affleck dressed as Bruce Wayne on the set of Suicide Squad, a film he was not originally thought to be part of.

It tells the story of a team of DC super-villains covertly put together by the government to go on extremely high risk missions in return for reduced prison sentences - so it makes sense the writers would bring in the man who can keep all these bad guys in check.

However the Dark Knight looked anything but intimidating as he felt his way around the set as blind as a bat for the early morning call time, before they finished filming at 5am.

Will Smith, who plays the assassin Deadshot, was also spotted on set chatting with director David Ayer.

The movie will also star Jared Leto as The Joker, Margot Robbie as his lover Harley Quinn, and Carla Delevigne as Enchantress.

Affleck's part in the film, set for release in August 2016, is likely to be small.

But five months earlier, he will have gone toe-to-toe with Henry Cavill's Superman in Dawn Of Justice, which will also serve as DC's introduction to the Justice League, where Jason Momoa's Aquaman and Gal Gadot as Wonder Woman are expected to be unveiled.

DC are eager to catch up with Marvel's runaway success with its cinematic universe, centered around its Avengers movies.
