Arnold Has No Accent
It’s clear that Noriyuki “Pat” Morita is an Asian man, but he had no accent. He was born and raised in California, and his English was perfect. However, the director of the show told him that his fans wanted to see him with an accent, and he’d need to pick one before they began filming so that people believed he was who he was portraying on the show. That’s where he would then create his own very over-exaggerated Asian accent.
