Bob-Waksberg revisited his evolution on the Diane Nguyen character, played by Alison Brie, in a late-night Twitter thread on Tuesday night. Bob-Waksberg had previously discussed the casting with Uproxx, Vulture and Slate. His thread was posted hours before Jenny Slate and Kristen Bell quit their respective biracial character roles on Big Mouth and Central Park. "The intention behind the character is I wanted to write AWAY from stereotypes and create an Asian American character who wasn't defined solely by her race. But I went too far in the other direction. We are all defined SOMEWHAT by our race! Of course we are! It is part of us!, he tweeted, adding: "We should have hired a Vietnamese writer, and a Vietnamese actress to play Diane - or if not that, changed the character to match who we did hire."
