#Q ORIGINAL QUESTION

Regarding the film Jaws (1975), are there any scenes that were improvised by the actors, and if so, which ones?

#T NARRATIVE TIMELINE

Act 2
Context: Medium
Brody sits at the dinner table feeling defeated; his son Sean mimics his movements and gestures in a quiet moment of bonding.
This scene is widely documented as being improvised by Roy Scheider and the child actor (Jay Mello) to build character rapport. The AI Summary incorrectly implies no other impactful/documented improvised scenes exist.
Act 2 (The Orca)
Mentioned Context: Medium
While chumming the water, the Great White Shark rears its head out of the water for the first time in full view of Brody.
While the line was improvised, the claim that Scheider's reaction was 'genuine surprise' (implying he was actually startled by the prop) is a common myth. The line 'You're gonna need a bigger boat' was an inside joke among the crew regarding the small support barge used for equipment, and Scheider inserted it into various takes deliberately.
"Scheider's initial reaction was genuine surprise"
Act 2 (The Orca)
Mentioned Context: Low
Brody backs into the cabin and tells Quint, 'You're gonna need a bigger boat.'
The attribution of the line as improvised is correct, though the motivation (genuine surprise vs. calculated inside joke) is mischaracterized in the summary.
""You're gonna need a bigger boat": This line... was indeed improvised."

During filming (1974)
Filming
The dinner table scene where Sean mimics Brody's movements is improvised on set after Scheider noticed the child actor mimicking him between takes.
The summary claims other adjustments were 'minor' and 'not as impactful', overlooking this famous unscripted character moment.

#M ANNOTATED LLM RESPONSE

While the script for Jaws was heavily rewritten and shaped during production, there is one famously improvised moment that stands out, and it has become iconic.

It's important to note that while other minor adjustments and line readings likely occurred spontaneously during filming, they weren't typically as impactful or widely documented as Scheider's "bigger boat" line. The essence of other scenes remained largely true to the rewritten and evolving script.

#F CORRECTION FEED (CLICK TO SEARCH)

[1] While the 'bigger boat' line is the most famous, the film contains several other significant improvised moments that are equally 'iconic' to fans and historians, such as the dinner table scene.
[2] Roy Scheider confirmed in numerous interviews that he ad-libbed the line.
[3] The line was not a spontaneous reaction to the shark; it was a running gag among the crew because the production's support barge was too small. Scheider had inserted the line into several other takes before the one that made the final cut.
[4] Spielberg and editor Verna Fields found the line perfect for the moment and retained it.
[5] The dinner table scene where Sean Brody mimics his father was entirely improvised and is considered one of the most impactful character moments in the movie. Additionally, Quint's toast 'Here's to swimmin' with bow-legged women' was an ad-lib by Robert Shaw.

#O MISSED POINTS & OVERSIGHTS

High
The dinner table scene where Brody's son mimics him was improvised.

This is one of the most famous behind-the-scenes stories of the film and a key character moment.

Medium
The 'bigger boat' line was an inside joke about the production's small support barge.

The summary incorrectly attributes the line to 'genuine surprise' rather than a calculated use of a set-wide joke.

Medium
Robert Shaw ad-libbed the 'bow-legged women' toast.

This is another iconic line that was not in the script.

Low
Robert Shaw's 'Mary Lee' joke to Ellen Brody was improvised.

A minor but documented ad-lib where Shaw was told to simply 'annoy' the character.
