The Suicide Squad cast have got matching tattoos.

Jai Courtney and the film's director David Ayer have had the word 'SKWAD' permanently inked on their bodies, with co-star Joel Kinnaman sharing a picture of Margot Robbie, dressed in full costume, inking David's arm.

Will Smith also tried his hand at giving his cast-mate a tattoo, although it didn't go too well according to Joel.

He captioned a photo of Will and himself: "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. #suicidesquad #willsmith #harleystattooparlour (sic)"

And inking each other's tattoos isn't the first unusual gift they have given each other after Jared Leto sent his co-stars live rats when they first started shooting the action film.

Adam Beech shared: "[Jared] sent [Margot] a nice love letter with a black box with a rat in it - a live rat.

"It was beautiful. Then he sent bullets to Will [Smith] with a letter."

Of a video Jared sent alongside the presents, he explained: "Basically, what he said was, 'Guys, I can't be there but I want you to know I'm doing my work as hard as you guys.'

"The video he showed is in character. It blew our minds away. Then we realised that day, this is real."
