Murphy plays the mild-mannered Norbit, his tyrannical obese wife Rasputia in a fat suit, and the orphanage owner Mr. Wong; the central conflict pits Norbit's escape from Rasputia's controlling, abusive marriage against his reunion with childhood sweetheart Kate. The plot follows classic romantic-comedy beats of self-assertion and true love with no identity-politics framing, systemic-oppression narratives, or lectures on gender, race, or norms.

All characters are original creations with no established-character race or gender swaps, no LGBTQ+ focal points, and no DEI casting mandates of any kind. Contemporary criticism targeted the film's political incorrectness and offensiveness, not any progressive content, while the movie achieved solid box-office returns despite receiving Razzies. The absence of activist intent or framing keeps the entire production free of thematic centrality around identity issues, allowing the stereotype-driven comedy to stand on its own without any overlay of modern social messaging or creator statements pushing ideological points.
