While the film Holes (2003) stayed remarkably faithful to Louis Sachar’s novel (largely because Sachar himself wrote the screenplay), several key scenes and character traits were improvised or heavily influenced by the actors' ad-libbing.
The most notable instance of improvisation occurs during the scenes on God’s Thumb, where Stanley (Shia LaBeouf) and Zero (Khleo Thomas) are resting and eating onions.
Jon Voight's portrayal of Mr. Sir was highly experimental, and he brought several improvised elements to the character to emphasize his "tough guy" overcompensation.
While not an "on-the-spot" ad-lib during a take, Sigourney Weaver (The Warden) specifically improvised/suggested a change to the film's ending that wasn't in the original plan.
The actors playing the boys in D-Tent (X-Ray, Armpit, Zigzag, etc.) were encouraged to bring their own "flavor" to their group interactions.
| Scene / Element | Actor(s) | Specific Detail |
|---|---|---|
| Zero’s Backstory | Shia LaBeouf & Khleo Thomas | Ad-libbed dialogue to build chemistry on God's Thumb. |
| "It Ain't" Line | Jon Voight | Improvised retort regarding his name, Marion. |
| Sunflower Seed Habit | Jon Voight | Amplified the aggressiveness of the spitting for character effect. |
| The Warden's Ending | Sigourney Weaver | Requested the addition of her seeing the treasure in the car. |
| D-Tent Banter | Group Cast | Various unscripted jokes and "attitude" during group scenes. |
The summary missed that Louis Sachar (the author) improvised his own line during his cameo as Mr. Collingwood ('My head feels like a cantaloupe' or similar reaction to the onion cream).
Several scenes in Holes (2003) involved improvisation. Most notably, Khleo Thomas (Zero) and Shia LaBeouf (Stanley) improvised the emotional dialogue on God's Thumb where Zero discusses his mother; director Andrew Davis instructed them to discard the script for that sequence to achieve authenticity. Sigourney Weaver (The Warden) also influenced the ending by requesting the unscripted moment where she is allowed to see the treasure in the police car before being driven away. Additionally, the cast members (the D-Tent boys) wrote and performed the credit song "Dig It" themselves. While Jon Voight's line "It ain't" is a famous movie addition not found in the book, the claim that he improvised his sunflower seed addiction is incorrect; that trait is drawn directly from Louis Sachar's novel.
