On some Pixar movie (Ratatouille, I think), one of the DVD extras was a set of deleted scenes that happened to be the <i>entire</i> work of individual animators - basically they spent 18 months of their life working on that stubble, and the whole guard was cut because that didn&#x27;t work with the story.<p>That&#x27;s an extreme, but something like that is possible for anyone working on a sufficiently large project. I get how people like that could really feel like their time was wasted - your assumption is that their contribution will be in the final project in a small but interesting way, and that&#x27;s not an assumption that can always be made.
