一部电影从剧本到最终完成的影片需要经历三个阶段，即前期制作、拍摄制作和后期制作。

A movie will go through three stages in order to get from a movie script to a finished movie. These stages are pre-production, production and post-production.

伊万没有双臂的那场戏是由两组镜头合成的：一组镜头拍摄空的床，另一组镜头拍摄躺在床上、手臂戴着绿色手套(后期制作时被盖掉)的阿什顿·库彻。

The scene where Evan has no arms was achieved by using two shots: one with an empty bed, and one with Ashton Kutcher lying in the bed with green gloves on his hands (which were erased later).

坏的，甚至只是普通的照明是不是可以被固定或在后期制作提高，必须在完成拍摄时的各种权利。

Bad or even just ordinary lighting is something that can not be fixed or enhanced in post production, it must be done right at the time of shooting.
