For the CBS series True Lies, about halfway through post we realized that instead of a main title sequence, we needed a short clip to explain the series.
As it always happens, by the time we figured out what we needed, it was way too late. So I had an afternoon to pull a cut together to pitch everyone involved on what we needed. With only footage from 4-5 episodes and a script from the showrunner, I built this as a proof of concept that turned into a final cut.
