Peter Capaldi’s role as The Thinker was one of the more surprising elements of The Suicide Squad. The Doctor Who star looked like he spent more time in hair and makeup than he did in the movie, with only a few scenes but one of the most bizarre and distinctive looks in the whole movie. That look apparently evolved over time somewhat, and yesterday, filmmaker James Gunn shared a photo from production that shows a slightly different take on The Thinker’s “upgrades” – the circuits, tubes, and knobs that protrude from his head in the film, in spired by his look from the comics.

First screen test of #PeterCapaldi as #TheThinker, Gaius Grieves. The careful observer will notice that the wires & the size & shape of some of Thinker’s “upgrades” are different from our final version in #TheSuicideSquad. @SuicideSquadWB pic.twitter.com/6cJXqiUp1F
