This was a spec spot written by freelance creatives Brett Landry and Brian Engleman.  They approached Mad Box in early 2014 to shoot and do the post for the spot. Chris Williams, co-owner of Mad Box, directed it. I was fortunate enough to be a part of the process by working on the character design, rigging and animation of classic characters Grimace and Hamburglar. Charles Bevan did the compositing and other VFX. The webpage dedicated to this work, including press links and interviews, is here.

I used Cinema 4D R16 for the modeling, rigging, hair dynamics and animation of both characters. 

Here's the VFX Breakdown video put together by Charles Bevan.
