The Classic Batman Villain That Has Fans Pausing A New Suicide Squad Featurette

James Gunn is clearly trying to bring as many obscure characters to the forefront of the DC Extended Universe with "The Suicide Squad." The best example is Polka-Dot Man (David Dastmalchian), who's front and center in the team alongside other lesser-known, equally bizarre villains like Javelin (Flula Borg) and Blackguard (Pete Davidson). Even the well-known characters Harley Quinn (Margot Robbie) and King Shark (Sylvester Stallone) are still pretty weird next to the typical heroes audiences are used to watching in the DCEU. This is all without mentioning the fact that this time around, the squad is up against Starro the Conqueror, a giant neon-pink starfish from outer-space. Standard stuff.

Of course, Gunn already has experience with handling an eclectic group of characters on the big screen, thanks to directing both "Guardians of the Galaxy" and its 2017 sequel over in the Marvel Cinematic Universe. But he's clearly taking his chance to play with as many DC toys as possible with both "The Suicide Squad" and the future "Peacemaker" series for HBO Max focusing on John Cena's character.

Really, it isn't surprising that he's cramming plenty of villains into his DC projects to widen the scope of his presence in the DCEU. In fact, a new featurette for "The Suicide Squad" just revealed a classic Batman villain in the film, played by a surprising actor.

The new featurette released on Twitter shows director James Gunn and the cast going through what makes their characters tick, as well as what to expect from the film itself. In a blink-and-you'll-miss-it moment, Sean Gunn — who also plays Weasel in the movie — can be seen as the classic Batman villain Calendar Man. 

It's obvious that's who Gunn is playing: The character's signature head tattoo, which features all the months of the year, gives it away. Calendar Man's typical schemes involve murders or robberies that take place on specific events throughout the calendar year. Based on what's shown in the featurette, within "The Suicide Squad," Calendar Man is imprisoned at Belle Reve along with the rest of the team; he's dressed in the same bright orange prison outfit they are. 

Surprisingly, there's another, deeper connection to Calendar Man in the film. Polka-Dot Man himself, David Dastmalchian, voices the villain in "Batman: The Long Halloween Part One" and "Part Two," based on the story of the same name by Jeph Loeb and Tim Sale. Since the featurette includes only a tiny glimpse of Sean Gunn's Calendar Man, it's not clear how big the character's role will be in the film.

One question many fans had was who the person next to Calendar Man in the shot is. It looks like Double Down, a villain who has a magical deck of cards embedded in his skin that he can rip out and use as weapons. For the moment, it's not clear who's playing him in "The Suicide Squad," as the villain isn't listed on the film's IMDb cast list. Double Down is traditionally one of the Flash's villains, although he is also one of the countless supervillains who causes havoc for Green Arrow and Black Canary at their wedding in the 2007 one-shot comic "Wedding Special" written by Judd Winnick.

It looks like fans will have to wait until "The Suicide Squad" drops in theaters and on HBO Max on August 6 to figure out what this pair's deal really is.
