The Big Mouth (1967) Timeline Explained – Every Event in Order

Gerald kills Syd because the gangster is a dangerous criminal who has stolen diamonds from dangerous people and is threatening his life. After Syd hands over the diamond map and reveals the location, Gerald decides it's safer to eliminate the threat permanently rather than leave a criminal alive who could identify him or go after the diamonds himself. The decision also silences any potential witnesses to the chaotic events on the beach.

The gangsters have nervous breakdowns because Gerald is an identical lookalike to the dead Syd Valentine. When they encounter Gerald at the hotel, they believe they are seeing a ghost or that Syd has returned from the dead. This psychological shock causes bizarre reactions, one imagines he's a dog, another transforms into a Larry Fine lookalike, and a third begins stuttering uncontrollably.

Foreshadowing: The movie establishes early on that Gerald and Syd are nearly identical, making the gangsters' later reactions believable.

The man who claims to be an FBI agent and believes Gerald's story is actually an escapee from an insane asylum, not a real federal agent. He poses as an FBI agent to gain trust and access to information. This revelation adds another layer of deception and danger to Gerald's situation, as he loses his only apparent ally.

The Chinese smugglers are a rival group who had also made a deal with Syd Valentine to purchase the stolen diamonds. They smuggled the diamonds disguised as plastic pearls, attempting to retrieve them during the chaos at Sea World. This creates a three-way conflict between Thor's mob, the rival gangsters, and the Chinese smugglers all pursuing the same diamonds.

Foreshadowing: Syd Valentine mentions making deals with 'other gangsters,' which establishes multiple parties were involved in the diamond theft.

Suzie rescues Gerald by arriving in a helicopter and lowering a rope ladder while he's being pursued by the gangsters at Sea World. Gerald climbs onto the ladder and escapes, leaving the confused mobsters behind. This dramatic rescue marks the turning point where their relationship truly develops and they escape the danger together.

Syd Valentine reappears at the end because he was not actually killed by Gerald, despite being shot, he somehow survived. The film leaves his survival unexplained, treating it as another absurd plot twist. When he surfaces in the Pacific Ocean, the rival gangsters immediately chase him into the water, resuming their pursuit of both Syd and the diamonds.

Foreshadowing: The movie's comedic tone allows for such impossible survival, though there are no explicit hints earlier.

The diamonds are never found because the various pursuers kill each other off during the chaotic chase while the diamonds remain hidden according to Syd's map. Gerald ultimately walks away with Suzie without locating the diamonds, choosing love over the dangerous treasure hunt. The unresolved heist is part of the film's comedic absurdist nature.

Gerald disguises himself to avoid recognition by the gangsters who are searching for him and the stolen diamonds. The disguise, modeled after Professor Julius Kelp from The Nutty Professor, allows him to move through the hotel undetected while continuing his search. It also helps him evade hotel detectives after he accidentally injures the manager.

The police ignore Gerald's story because it involves a complicated web of gangsters, stolen diamonds, and a man who looks exactly like a dead criminal. His claims sound absurd and unprovable without evidence. Additionally, Thor's mob has enough influence to make Gerald's account seem like fantasy or an elaborate cover story.

Thor and his mob are left chasing Syd into the ocean during the chaotic finale at Sea World and the Pacific. After Gerald and Suzie walk away together, Thor and his remaining gangsters are presumably still pursuing the diamonds through the water. Their fate is left ambiguous as the film shifts to the romantic conclusion.

The narrator, who posed as Bogart throughout the film, reveals himself as Frank De Vol in the final scene as a comedic twist. He walks away on the breakwater wearing a business suit without trousers, carrying a briefcase. This absurd ending fits the film's comedic tone and pokes fun at classic film noir narrators while providing a final laugh.
