#Q ORIGINAL QUESTION

Regarding the film Hercules (1997), are there any scenes that were improvised by the actors, and if so, which ones?

#T NARRATIVE TIMELINE

Pre-Production / Voice Recording
Context: High
James Woods is cast as Hades and extensively improvises during recording sessions, changing the character from a slow, menacing figure to a fast-talking Hollywood agent type.
James Woods is the most documented improviser in the film. His ad-libs (e.g., 'Name is Hades, Lord of the Dead. Hi, how ya doin'?') redefined the character's animation style. The AI Summary completely omits him.
Act 1
Context: High
Hades discovers his minions failed to kill Hercules 18 years prior.
James Woods improvised the famous line: 'I've got 24 hours to get rid of this bozo, or the entire scheme I've been setting up for 18 years goes up in smoke, and you are wearing his merchandise!'
Act 2
Mentioned Context: Medium
Hercules becomes a celebrity hero in Thebes, a sequence set to the song 'Zero to Hero' performed by the Muses.
'Zero to Hero' is primarily a musical number by the Muses. While Phil has a line of dialogue ('You go from zero to hero'), characterizing it as an improvised 'spiel' by Danny DeVito is incorrect; it is the film's central scripted theme.
"It is likely he did some adlibbing on that scene, especially with his 'from zero to hero' spiel."
Throughout Film
Mentioned Context: Low
Pain and Panic (Bobcat Goldthwait and Matt Frewer) interact with Hades.
This is accurate, but the improvisation was largely driven by their reaction to James Woods' ad-libs, which the summary fails to mention.
"The scenes with Hades' bumbling minions, Pain and Panic, likely contain some degree of improvisation."

#M ANNOTATED LLM RESPONSE

While it's difficult to know for absolute certain every single improvised moment without behind-the-scenes confirmation, I can point to a couple of areas in Hercules (1997) where improvisation seems highly likely, based on the actors' comedic styles and the general flow of the scenes:

It's important to note that animation presents a unique challenge to improvisation. Unlike live-action films, animators need to work from a pre-determined soundtrack, therefore the amount of improv is limited. The actors would probably have recorded many takes with different tones, and they might've improvised during those takes. The animators would then have chosen the best moments to use in the final film.

#F CORRECTION FEED (CLICK TO SEARCH)

[1] The summary fails to mention James Woods, whose performance as Hades is the most famous example of improvisation in the film. Woods ad-libbed so much that the character was completely reimagined from a slow, menacing villain to a fast-talking 'used-car salesman' type.
[2] Directors Ron Clements and John Musker have stated in interviews that they encouraged Danny DeVito to ad-lib to bring a specific 'New York' energy to the character of Philoctetes.
[3] While DeVito likely ad-libbed during training scenes, 'Zero to Hero' is the title of a major musical number and a central theme of the movie. It is unlikely the 'spiel' was a spontaneous ad-lib rather than a scripted thematic element.
[4] Bobcat Goldthwait and Matt Frewer recorded their lines together in the same booth, which is rare for animation, specifically to allow them to play off each other and improvise their bickering.
[5] In traditional 2D animation, the voice track is recorded first so that animators can synchronize the character's lip-sync and body language to the actor's performance.

#O MISSED POINTS & OVERSIGHTS

High
James Woods as Hades

James Woods is the primary example of improvisation in Hercules. He spoke so fast and ad-libbed so much that the character's design and the film's overall tone were altered to accommodate him.

Medium
Hades' Temper Tantrums

Specific scenes where Hades loses his temper and says lines like 'I'm fine, I'm fine, I'm cool, I'm fine' were largely ad-libbed by Woods.
