Jared Leto and Mark Ruffalo found the perfect way to roam the floors of New York Comic-Con this weekend, donning some extravagant disguises which rendered them completely unrecognisable. Both actors then shared pics of their new looks on social media, posing with fans who had no idea they’d just met two Hollywood stars.

Leto's costume was comprised of a large baboon mask, which changed the handsome actor into something much more terrifying. He then roamed the floors of the convention in full baboon character and posed for pics with other attendees.

The actor, who plays The Joker in the upcoming Suicide Squad movie even found a fan cosplaying as The Joker to pose with, sharing the pic on twitter with the caption ‘he had no idea’. Leto has been spending the past few months filming the upcoming super villain film, sporting dying green hair and silver teeth for his incarnation of the Batman villain.

Meanwhile Mark Ruffalo, who’s best known as the Incredible Hulk in the Avengers films, chose to wear what can only be described as an ‘ugly old man’ mask, to keep his identity a secret. The mask included a large black moustache and over-sized mouth complete with a drooping cigar.
