Naomi appears to be a hardworking actress with a tendency to become obsessive about authentically portraying the role.
She also claims she is frustrated because she wanted to portray a more lighthearted character rather than a serious, more complex role.
Naomi is a human woman with early signs of aging on her face. She wears her hair back in a blonde ponytail with long bangs framing her face.
Her everyday attire is a plain white blouse with a scoop neck and sleeves that go up to her elbows, deep green cargo pants, brown belt, and ankle-length brown boots and a navy infinity scarf.
To play Diane in Mr. Peanutbutter's Hollywoo Heist, she wore a polo-style cropped button-down shirt, a cropped green jacket with red arrows looping away from her abdomen, dark blue jeans with two front pockets, brown belt, and black ankle-length boots with a yellow stripe going across them.
Naomi is shown obsessively stalking the real Diane to get into the character she is playing. Diane eventually tells her she should talk to BoJack because "Diane doesn't spend time interacting with Diane—she talks to other people."
Naomi in-character then starts a temporary fling with BoJack on set. Later, when she is fired from the project she tells BoJack he was having an affair with "Diane," not Naomi. She explains that she has become herself again and that herself as Naomi finds BoJack "kind of gross." She then kisses him to prove her point saying, "See? Nothing."
Following that, she leaves Mr. Peanutbutter and Diane's house.
As for the film itself, it goes through so many wacky changes throughout the episode, that the end result is not even a film at all but a gift basket.
