导演兼编剧皮特·多克特（Pete Doctor）负责皮克斯最受欢迎的一些电影——他执导了《怪兽公司》（M***ters，Inc.）和《玩具总动员》（Toy Story）等。昨天，他花了几个小时回答了Redditors的问题，就写作过程、角色以及导演一部动画片的具体意义给出了一些精彩的评论。”“你是不是站在某个动画师的肩膀上说‘萨利看起来很悲伤，但他应该看起来闷闷不乐’？”一位评论人士问道。医生回答说：

Around here, a director usually comes up with the concept and then shepherds that idea along all the way until its done. He/she may write, draw, animate, or do voice work, but the primary job is to be able to communicate to the 400+ amazingly talented people who do the actual work. I have to clearly state what it is I'm looking for from the animation in this shot, or what the fire effects should look like in this other shot. Because animation is done in pieces, you seldom have the benefit of seeing what the movie (much less an individual shot) will look like until it's all done, so you have to have a good imagination. But more important than all of that — I'd say the majority of my job is creating a story and characters that people care about.

他说，忙碌的导演过程帮助我们了解到：

[Up] was a combo of doing something with a grouchy old man character (which just seemed fun) and my own feelings of wanting to escape the world. Nobody warned me that as a director basically all I do is run around and talk to people all day, and I'm not an extrovert... so by the end of the day I usually wanted to crawl under my desk. That feeling of getting away from the world led to the story of Up.

AMA中途被医生大楼的火警打断，现在已经结束了，但Reddit上有很多好东西。
