DC has released its first movie in 3 years, Batman v Superman: Dawn of Justice is supposed to jump start the DCEU which began with Man of Steel. In August the villains will get their story with Suicide Squad; the world's worst criminals are offered reduced sentences in exchange for undertaking the most dangerous black ops missions imaginable. Considering how much we learned about Batman v Superman in the run up to its release, the makers of Suicide Squad are playing it super secret squirrel!
This is mostly speculation but there are some possible spoilers. Firstly, is this movie set before Batman v Superman? Ben Affleck's Batman is older and bitter, will we see this in Suicide Squad? Assuming Batman knows about the squad or Task Force X as it's also known, does its existence contribute to his bitterness? Especially considering the only reason these criminals - all of whom hold a grudge against Batman - were available for the task force is because Batman caught them. We know that in Suicide Squad, Batman goes after the Joker and Harley Quinn, is this his only involvement? Is he just part of Harley's origin story or will we see origin/back stories for multiple characters and Batman's involvement in their incarceration? Jeremy Irons is rumoured to be involved, which could indicate a larger role for Batman. Either that or he's just providing assistance from the Batcave as he does in Batman v Superman.
Notice the 'J' under his left eye
The comic book character Deadshot is said to be very different to the one in the movie. In the comics Deadshot A.K.A Floyd Lawton is a ruthless assassin who will kill anyone for money, except Batman. He learns that if Batman appears he should give up immediately. Batman is the only man Deadshot fears, having tried and failed to kill him so many times. But in the movie, Deadshot apparently has a bit of a conscience, he takes one last job to get out of the life and spend time with his daughter. But the job goes wrong and he ends up in Belle Reve Prison. I'm guessing the Suicide Squad offers him a chance at redemption as well as a reduced sentence of course. The changes have probably been made by/for Will Smith who always seems to play this sort of character. He may be bad, but there's some good to him. Smith's look is interesting; with a customised AR-15 rifle, modified Glock 17 sidearm and custom armour with modified Glock 17's mounted on each forearm and plenty of extra magazines for both rifle and sidearm. Also he looks like a young, slim Uncle Phil from The Fresh Prince of Belair!
Margot Robbie is playing Harley Quinn, the Joker's psychotic groupie girlfriend. We will get to see her transformation from Psychiatrist Doctor Harleen Quinzel to psychotic Harley Quinn at the hands of her Mr J.
Very little is known about Scott Eastwood's character; he's a soldier (possibly special forces operator) assigned to the team, that's all we know. The patches seen below could be a clue to his character's identity or background. "GQ" is likely some sort of nick name; it could relate to either the mens magazine (Gentlemen's Quarterly) or the US Navy readiness level "General Quarters", so either he's stylish or US Navy...or both. The other patch I'm guessing is some kind of unit insignia, possibly a fictional one for Task Force X or Suicide Squad. Please leave a comment below if you recognise or have knowledge of either.
It has been speculated that Eastwood is playing either Dick Grayson or Slade Wilson. Wilson was a soldier who became Deathstroke; a super soldier or metahuman who's abilities are enhanced by a super serum. He has the strength of 10 men, heightened speed, stamina, reflexes and endurance, and the ability to use 90% of his brain. Deathstroke was shot in the head causing him to lose sight in his right eye. This should be something to look out for if Eastwood's character hasn't been revealed. If Eastwood is playing Dick Grayson he's probably known as Agent 37. In the comics Grayson faked his death, after which Batman tasked him with infiltrating the organisation known as Spyral where he worked under the codename Agent 37. Batman was interested in Spyral's activities unmasking superheroes. It makes sense that if Batman is aware of Suicide Squad and what they're up to that he would want to keep a close eye on them. However, it would be monumentally difficult for Grayson to infiltrate the government or military units attached to Suicide Squad let alone getting on the team itself. Either that or Batman has kidnapped Mystic Meg and got Grayson to join the US military years ago! There's a possibility that he's just a soldier and is being singled out because he's recognisable and he's worked with Director David Ayer before on Fury. Given the information I have I'd say Eastwood is more likely Slade Wilson than Dick Grayson, but at this point I'm not entirely sure he's one or the other.
Amanda Waller (Viola Davis) is the government official who assembles Task Force X. She's the boss. As Waller puts it; "getting people to act against their own self interest is what I do for a living."
Colonel Rick Flag (Joel Kinnaman) is the soldier that leads the team on the ground, not everyones dream job! I believe he reports directly to Waller.
Katana (Karen Fukuhara) wields the Soultaker blade which traps the souls of its victims within the sword itself. She isn't a criminal like the others, she's a volunteer and Rick Flagg's bodyguard.
"Find your inner shit bag" is the advice given to Jai Courtney by Director David Ayer. Boomerang is a brawler with a beer holster and some ridiculous weaponry, including some boomerangs I guess.
El Diablo is able to create fire, he's also a former Los Angeles gang banger who wants to stay out of the fight. Waller keeps him in a floodable cell at Belle Reve for obvious reasons.
Killer Croc suffers with a rare skin condition that has left him with reptilian skin. Adewale Akinnuoye-Agbaje describes him as "a cannibal with rage issues". Croc is also picky, he apparently only eats very talented people.
Slipknot (Adam Beach) is a mercenary/assassin who is very good with rope, even using it as part of his fighting style. According to Beach, Slipknot is the team's "escape plan", able to get them out of trouble.
What the members of Suicide Squad will have to face is being kept very secret, the image above is one of the only clues. You can see Harley and possibly Katana standing on the left at the bottom of the stairs. I've never read any of the comics so I have no idea, it could link to Justice League and possibly Bruce Wayne's dream/vision of the future in Batman v Superman. The fact that there's several creatures standing around what ever that thing is doesn't really help, it could be a weapon or some kind of portal for inter-dimensional or inter-stellar travel, it could be the movie's main villain. Whatever it is, it looks like the convicts will earn those reduced sentences!
