Re: [新聞] 美國隊長玩特效伊凡紙片人操出大肌肌

[dan800512 (丹水人)]

抱歉有點lag...只是小弟一直心存懷疑，到底是如台灣記者所寫的「頭部替換」技術
（類似班傑明的奇幻旅程，把臉移到不同的軀體上）還是是同一個人演只是用特效改？

IMDB上說：（http://www.imdb.com/title/tt0458339/trivia?tr=tr1522111）

    Contrary to popular belief, a body double was not used for Chris
    Evans for the scenes when he was skinny. The filmmakers had
    originally planned to hire a body double and superimpose Evans'
    face onto the double's body, but ultimately scrapped the idea
    since director Joe Johnston claimed that Evans moved in a unique
    way and that no body double could replicate his movements. 
    Ultimately, the filmmakers utilized digital technology to "shrink"
     Evans down, essentially erasing portions of his physique, until
    they came up with what the filmmakers called "Skinny Steve". Over
    250 shots were filmed like this, and because the shrinking process
     left empty space in the background, many of the scenes had to
    filmed in front of a green screen so that they could superimpose
    the backgrounds back into the scene.

    大致上就是說原本是要用班傑明的方式，把頭移到替身上，但後來因為導演
    覺得克里斯伊凡有自己很獨特的一套行為舉止，所以最後用電腦特效，把整
    個人全身縮小塗抹。

Wikipedia上說：（http://tinyurl.com/42w9ncj）

    The technique involved shrinking Chris in all dimensions. We shot
    each skinny Steve scene at least four times; once like a normal
    scene with Chris and his fellow actors in the scene, once with
    Chris alone in front of a green screen so his element could be
    reduced digitally, again with everyone in the scene but with Chris
     absent so that the shrunken Steve could be re-inserted into the
    scene, and finally with a body double mimicking Chris's actions in
     case the second technique were required. When Chris had to
    interact with other characters in the scene, we had to either
    lower Chris or raise the other actors on apple boxes or elevated
    walkways to make skinny Steve shorter in comparison. For
    close-ups, Chris' fellow actors had to look at marks on his chin
    that represented where his eyes would be after the shrinking
    process, and Chris had to look at marks on the tops of the actor's
     head to represent their eyes. ... The second technique involved 
    grafting Chris's head onto the body double. This technique was
    used mostly when Chris was sitting or lying down, or when a
    minimum of physical acting was required.

    大致上是說他們使用了兩種方式。第一種是在比較互動式、動態的場景上，
    使用IMDB所說的縮小特效，透過每個版本的覆蓋刪減來替換成縮小版的人。
    第二種方式則是類似班傑明，將他的臉部移轉到一個身體替身，大部分用在
    靜態場景，或當角色採取坐臥的姿勢。

Chris Evans 在一場採訪中也表示（http://tinyurl.com/3m3q9br）


    "It was a crazy process doing that stuff. They went back and forth
     on the type of technology they were going to use. Initially, they
     were just going to do body shrinking, and then they thought,
    'Well, maybe we can get another skinny actor and put Chris' head
    on it,' and I really, really was against that. I said to Joe
    [Johnston, the director], 'Look, I know we want this to look good
    and this effect to not be distracting from the film, but it has to
     be my performance. I don't want to share this. Your body is a
    huge piece of the acting puzzle, and I don't want to have somebody
     else's body tell the story that I'm trying to tell.'"

    他自己是說他不希望由替身來「表演」自己的故事，所以說服導演讓他自己
    演瘦小部分的戲，也就是並非只有臉部表情，而是整個身體都是他自己的。


爬過文好像沒看到有比較深入的討論，但因為最近也有朋友看完在問，於是我就大膽
提出來，請版眾幫我看看到底是怎麼做的。謝謝大家。
