The Animatrix seems like a real example of something along those lines. A DVD of 6 short episodes that expanded on the Matrix story universe. They were done by different directors&#x2F;writers&#x2F;makers, like authorised fanfic or something. In my opinion it was a great addition, better than the full-blown sequels, and certainly not a distasteful cash-grab.<p>I think this could totally work for something like Inception too. The film has a backstory suggests at a wider context beyond what&#x27;s shown in the scenes. Most stories do. That&#x27;s why fanfiction exists.
