Director David Ayer shared a photograph on Twitter.com showing the Australian actress, in character as the villain Harley Quinn, holding a tattoo needle over his arm while inking the misspelt word 'skwad' on the inside of his forearm.

Actor Jai Courtney also showed off an image of the phrase etched on his arm, while Will Smith was seen working on Joel Kinnaman's bicep in another snap posted on Instagram.com.

Kinnaman added in the caption, "Got my #skwad tattoo... Will has many many talents, tattooing is not one of them. It was like watching a drunk baby fly a helicopter."

It is not known if the body art is real or part of the movie.
