The incredible news that Robert Downey Jr. is in talks to bring Iron Man to Captain America 3 has set the Internet on fire, and with good reason, as the most likely story arc that Marvel will use in this casting scenario is Mark Millar's fabled Civil War limited series that ran from 2006-07. Nothing has been confirmed at this stage, but with the incessant rumors and leaks coming from people close to the project, it appears highly likely that Marvel will draw the basic storyline of Cap 3 from Civil War.
小罗伯特唐尼在访谈中说起美国队长3会有钢铁侠加盟，这个消息无疑向网络扔下了一颗重磅炸弹，而在这一部中最有可能出现的情节即超级英雄间的内战。目前这一消息还没有得到证实，但是内幕人士泄露出来的信息已经表现出了极大的可能性。

So what's the fuss about Civil War? Well, THR has put together five key things that occur in the comic series that could have heavy ramifications for Cap 3 as well the wider Marvel Cinematic Universe, future Ant-Man and Dr. Strange movies, and even planned Avengers sequels several years from now. Warning, major Civil War spoilers ahead. 
那么，内战期间发生了什么呢？我们汇集了五件事，它们关于美队三以及漫威、蚁人和奇异博士，甚至还会涉及到接下来的复仇者系列。以下内容会有剧透哦。

1. Civil War needs more than just Iron Man and Cap
1.内战不止涉及钢铁侠和美国队长

Millar's Civil War featured a huge number of Marvel characters who were forced to take sides following the introduction of the Superhero Registration Act, an American government initiative to regulate and control vigilantes, who also must reveal their identities. In the comics, Luke Cage, Human Torch, Invisible Woman, Daredevil, Cable, Nick Fury and Captain America rebel against this government attempt to control superheroes. In favor of the legislation you have Iron Man, Ant-Man, Spider-Man, Black Widow, She-Hulk, Mr. Fantastic and many others.
为了控制超能力者，美国政府引入了超级英雄注册法案，这标志着英雄的身份会被揭开，漫威超级英雄被迫选择立场。漫画中，卢克凯奇、霹雳火、隐身女侠、夜魔侠、链锁和美队反抗政府对超级英雄的限制；而以钢铁侠为代表的蚁人、蜘蛛侠、黑寡妇、神奇先生等人则站在政府一边。

2. Civil War features Ant-Man and Dr. Strange
2.内战塑造了蚁人和奇异博士

Both characters play their parts, to varying degrees, in the series, and with both slated to have their own stand-alone features, it looks like a Civil War-based Cap 3 could very well be the setup for the third phase of the Marvel Cinematic Universe. So expect the consequences of this film to run on into future Avengers sequels too. 
这两个角色都很好地表现了自己的部分，而且都有自己独特的性格特点。基于内战背景的美队3将会是满威宇宙电影的第三阶段。因此可以期待这部电影的角色同样会出现在复仇者联盟系列中。

3.Tony Stark is the villain
3.托尼史塔克成了反面角色

Iron Man lines up behind the government and is the chief advocate for the Superhero Registration Act; not only that, in Civil War, Stark doesn't seem all that concerned with locking up rebellious superheroes in inhuman conditions. Cap on the other hand feels the Act is dangerous government overreach and violates civil liberties. We're gonna have to face up to the fact that Stark will likely be the bad guy in any Civil War movie adaptation. However, the series also dealt with the moral ambiguity of the situation, with both Iron Man and Captain America coming at the issue with good intentions. 
钢铁侠支持政府采取超级英雄注册法案。不只如此，内战中他以不人道的手法将叛变的超级英雄一一抓起来。在对立面的美国队长认为这项法案是危险的，会使政府侵犯公民自由。我们必须面对的现实就是内战中，钢铁侠成了反面人物。然而，这个系列同样也涉及到一些道德模糊问题，包括钢铁侠和美国队长不同的观念。

4.Civil War is packed with superhero teams
4.内战中超级英雄有组队

There's the Avengers of course, as well as the New Avengers and the Mighty Avengers and not forgetting Cap's rebel alliance the Secret Avengers. Also making appearances are the villainous Thunderbolts, the Runaways, the Great Lakes Initiative, X-Factor and the X-Men. 
复仇者联盟当然还是存在的，一并还有新复仇者和强复仇者，以及美队的反叛联盟秘密复仇者。同样出场的还雷霆特工队、离家童盟、镭射眼等初代X战警以及后来的X战警。

5. Civil War sees the death of Steve Rogers
5.内战宣告了史蒂夫·罗杰斯之死

Yep, it happens. There's no getting away from it, the end of Civil War sees Cap get assassinated. After the end of the war, Stark assumes control of SHIELD.
是的，美队死了。影片最后美队被暗杀这是无法逃避的事实。内战结束之后，斯塔克取得了神盾局的控制权。
