I'd never seen Pitch Perfect before I got the sketch, actually hadn't even heard of it. I didn't know who Fat Amy was, was completely clueless as to what horizontal running was referencing. So I do what I usually do when I have no idea what something is: I call my younger sister. And then I Googled it. And once I figured out what I had been handed was more than a little intimidated.
I downloaded as many photos of Rebel Wilson as I could find and wondered all day what I was going to do. That night I watched the movie with my friend Cathy and found some kind of affection for pieces of the story and the characters, and with that tenuous interest developed I stumbled on an idea and ran with it.
The biggest problem was that I didn't have any photos of Rebel Wilson in the pose that I needed - and even if I did, I'm not sure what would and would not be considered plagiarism in using a photo of someone as inspiration for a final painting. I've also never done any kind of caricature (not that this was going to be one) or even tried to create a drawing of someone without good reference for what I was doing. But I ended up finding two photos with the same-ish lighting that were kind of what I was looking for and I did a sketch or two to see if I could combine them into what I was looking for.
A week is not a long time to throw something together, so there was no time for second guessing. It was close enough. Combined with a photo I took of myself in the pose I wanted, I think I managed pretty well.
