This is an idea I've been mulling over for a mashup of my favorite movie quotes and scenes. These films are pretty much always swimming around in my brain and I've always wondered what they'd look like swirled together. This is my best approximation.
For the most part I let the scenes play out in their original form and lined up the other clips with their interesting coincidences in edit points and content. The most challenging and fun part was keeping a continuous logical thread going.
