The film leaves Billie Booth’s death under suspicion. The later novel provides an answer that should not be confused with what the 2019 cut shows.
The answer depends on the version
In Once Upon a Time in Hollywood, we do not see Cliff Booth kill his wife. Suspicion arises in conversations and in a brief flashback scene that cuts away before the outcome. The novel written by Tarantino and published in 2021 does confirm that Cliff killed her. That difference allows for a precise answer: the film keeps the ambiguity; the book develops the episode and establishes his responsibility.
Billie Booth is played by Rebecca Gayheart. She is not Rumer Willis, who appears in the film as Joanna Pettet. The distinction matters because the wife has a very brief presence and it is easy to misattribute her face to another cast member. The character serves a specific function in Cliff’s story, but she does not have a standalone arc comparable to that of the protagonists.
Information from the book can enrich a later reading, even if it does not materially change the images released in 2019. A viewer who has only seen the film has less information than a reader of the novel. Treating both experiences as identical removes an essential narrative decision: Tarantino chose to show the threshold of an action on screen and leave out what would resolve the doubt.
The Once Upon a Time in Hollywood novel expands many aspects of the characters’ world. In this case, the expansion directly affects the moral judgement of Cliff. There is no need to transfer every detail of the literary passage to recognise its consequence: cinematic uncertainty there becomes a narrated fact. It is worth keeping that distinction in mind when discussing whether the film reveals, suggests or confirms a murder.
The weapon, the sway and the cut
The scene places the couple on a boat. Billie speaks with hostility and Cliff remains seated with a speargun. The direction of the object and the movement of the boat create an immediate expectation. The viewer understands that a death may occur, but the edit interrupts the moment before we see the decisive act and its consequences.
The lack of resolution does not mean there are no clues. The composition brings together domestic conflict and a tool capable of causing harm. Nor does it amount to full proof of intent. Precisely for that reason the scene is unsettling: it offers enough material to be wary, while removing the information that would allow the episode to be closed as an accident or deliberate attack.
The insertion belongs to the game of memories and flashbacks that characterises Tarantino’s non-linear narrative. It is not presented as a police file or as a thorough judicial reconstruction. It is a selected fragment within another situation. Its brevity obliges us to relate it to what other characters say and to the reputation that follows Cliff in his work.
The tone adds another difficulty. The dryness of the performance and the speed of the cut may produce a comic reaction, but the content remains a possible death within a relationship. Laughter does not prove innocence, nor does it make Billie someone who deserves violence. The contrast between form and seriousness forces us to observe how the film manages sympathy towards a protagonist who is already appealing.
A reputation that affects his present
The episode does not exist solely to feed an audience theory. Within the story, the suspicion harms Cliff’s job prospects. Some people do not want him around, and Rick has to defend him in an attempt to get him work. The uncertainty therefore has practical consequences even without a shown conviction: colleagues decide with whom they want to share a set.
Rick trusts his friend and tends to frame the accusation as a rumour. That stance characterises Rick; it is not an omniscient voice certifying what happened. Likewise, the rejection from other characters shows conviction without replacing the absent scene on its own. The film sets out opposing views so that the viewer can sense the distance between personal loyalty, reputation and knowledge.
Ambiguity complicates the portrait of Cliff Booth because it coexists with his patience, his ability to care for Brandy and his support for the actor. The character does not become transparent simply by doing likeable things. The question about Billie stops his charisma from becoming a moral guarantee, especially when he later proves that he can still be very effective when using violence.
The most rigorous reading keeps the two answers separate. The film leaves a suspicion deliberately open and allows us to discuss how it shapes our relationship with Cliff. The novel confirms the fact and shifts the discussion towards the contradictions of a character responsible for that death. Knowing more does not mean forgetting how the mystery was constructed: it lets us appreciate that each version asks the audience for a different kind of judgement. The literary answer resolves the event, but leaves intact the difficulty of judging the character as a whole.
