The animator revealed that he chose to direct the upcoming 30-minute A Matter Of Loaf And Death because it did not require as big a time commitment as Chicken Run and Curse Of The Were-Rabbit.
He explained: "I've done two-feature films back-to-back and each one has taken four years to do, at least. It's like a homecoming really, it's nice to be back with the BBC again. I just felt like I needed to get ideas out quicker and a half-hour format seems a lot more humane."
Park acknowledged that he was able to complete the new film in record time thanks to a large team of animators.
"The first Wallace And Gromit film A Grand Day Out, which was largely single-handed, took seven years to make - this one took seven months," he said.
A Matter Of Loaf And Death, which sees the Aardman Animation duo run their own bakery called Top Bun, airs this Christmas on BBC One.
