Tibbs is uninterested in glory or media attention. He is a perfectionist, and his sole motivation is duty and justice. In the films, Tibbs displays a considerably larger degree of anger over issues of race than in the books. For example, in the novel In The Heat of the Night, the phrase "They call me Mr. Tibbs" is a statement ending in a period, while in the movie, it's an angry exclamation.
Physically, Tibbs is slender, quick, strong, and handsome. His nose is relatively narrow, and his mouth is "straight and determined". His skin tone is neither exceptionally light nor dark.

"The chief has approved the release to you of the details concerning the Morales murder" she told me. He has authorized you to go ahead with it at any time, if you want to". Of course I wanted to: the unraveling of the case via the patient, intelligent investigation work of the department in general, and Virgil Tibbs in particular, would need no embellishment in the telling.
