Now this was a very interesting and peculiar project. I read almost four versions of the script for the movie and saw every single storyboard that was made for it. The first script was funnier, even tough the movie's final version looked GREAT! The curious thing is that we were working on the comic book adaptation while the movie was being filmed and animated at the same time!
We were sitting at the edge of our seats 24-7! Why? Because they were changing the scenes almost on a daily basis. I got addicted to Red Bull drinks and I never heard Joan Hilty's voice so many times in one day for almost two-three months!
My job was to keep the Looney Tunes look loyal to the model sheet while the Duendes Studio took charge of the 'real' characters.
