You remember the Marvel Cinematic Universe's World Security Council, right? The generic overseeing board who make very bad decisions, as seen in their first appearance in The Avengers where they decided to fire a great big nuclear missile at New York City. Great idea guys, just great.
They reappeared during last year's [Captain America: The Winter Soldier](tag:254973) as one of the driving forces behind the controversial surveillance and targeting satellite undertaking Project Insight, along with big bad HYDRA leader/spy Alexander Pierce (Robert Redford).
Following the supposed assassination of Nick Fury (Samuel L. Jackson) Pierce and the Security Council moved up the launch of Project Insight. When Pierce's status as a HYDRA agent was exposed by Captain America / Steve Rogers (Chris Evans) they were held as hostages by the aforementioned bad guy, until Black Widow / Natasha Romanoff (Scarlett Johansson) kicked the STRIKE team's collective asses.
However Pierce's back up plan, the exploding security badges worn by the council members, still took them out, leaving only Councilwoman Hawley (Jenny Agutter) still alive, though her current status is unknown.
The Ant-Man Post Credits Scene
So the Ant-Man post credits scene showed Captain America and Falcon / Sam Wilson (Anthony Mackie) finding the Winter Soldier / Bucky Barnes (Sebastian Stan) held in a dingy garage somewhere, and you may remember the conversation that the two Avengers have regarding Iron Man / Tony Stark (Robert Downey Jr.)
Sam Wilson: This would've been a lot easier a week ago...
Steve Rogers: If we call Tony...
Sam Wilson: No, he won't believe us.
Steve Rogers: Even if he did...
Sam Wilson: Who knows if the Accords will let him help?
So it's likely that "the Accords" will be the MCU's answer to the Superhero Registration Act of the comics, which makes sense given that they're related to Tony Stark somehow.
Given the role of the World Security Council thus far it would make sense that they'd be the governing body causing problems in [Captain America: Civil War](tag:994409), if not for the fact that the majority of their members just got blown the heck up (aside from Hawley and Gideon Malick who is still kicking about in [Agents of S.H.I.E.L.D.](tag:722469)).
So a popular rumour circulating right now is that rather than the World Security Council, it's going to be the United Nations who are brought in to control the Avengers. This seems likely when you look at the official cast list on IMDB, which lists a bunch of secondary actors portraying UN Delegates and Staffers.
Unless there's just gonna be a random UN summit during Civil War (which is also possible so, you'know) it does seem more than likely that they'll be the ones to step in to fill the shoes of the World Security Council, international incidents are UN territory after all.
And Martin Freeman's Mystery Character?
Well, Martin Freeman's role has been kept very close to his chest but he did say earlier this year that he'd be playing a character involved with the US government:
"[My character] works for the American government. He works in conjunction with the superheroes and certain agencies that help to tame the superheroes' power. You're not quite sure which side he’s on. It looks a little bit like he’s playing one game when actually he’s playing another."
Sounds kinda Coulson-ish to me, but fair enough.
It's been speculated that Freeman will be portraying Marvel character Henry Peter Gyrich, or at least a version of him. Gyrich was a CIA / NSA agent who acted as a government liaison to the Avengers team, so again a pretty Coulson-ish character and a perfect fit for a Civil War role.
If he's acting as liaison for the Avengers and the US government then he'd be the guy assessing the threat presented by the superheroes and taking that to the UN for review, which would explain the shades of grey over which side he's on as far as personal motives go. Could he be our surprise bad guy alongside Baron Zemo (Daniel Bruhl)? Guess we'll just have to wait to see for sure when Captain America: Civil War hits cinemas on May 6th 2016.
