Mini Lesson
An adaptation is a version of a story retold in a different medium. When a novel is turned into a film, the filmmakers must translate words on a page into images, sound, and performance. Because the two media work very differently, adaptations almost always involve changes — some small, some significant. Comparing a book to its film adaptation sharpens your understanding of both storytelling forms.
Common types of change in adaptation
- Compression — subplots and minor characters are cut to fit a two-hour runtime.
- Combination — two characters are merged into one to simplify the cast.
- Changed ending — the film gives a different conclusion, often more optimistic, for a wider audience.
- Relocated setting — time period or country is changed to suit the target market.
- Removed interior monologue — a narrator’s inner thoughts cannot be filmed the same way they can be read.
Why filmmakers make changes
- Medium constraints: film is visual and time-limited; it “shows” rather than “tells”.
- Audience: a film may target a different age group or cultural context than the original book.
- Budget: elaborate settings or large casts cost money; filmmakers simplify accordingly.
- Artistic interpretation: a director may have a distinct vision that extends or challenges the source text.
Comparing systematically: Venn diagram and side-by-side table
A Venn diagram works well for a quick visual overview: book-only features in the left circle, film-only in the right, shared elements in the overlap. A side-by-side table is better for detailed comparison: each row covers one element (character, setting, theme delivery, ending) with a column for the book and a column for the film.
Forming an evaluative opinion
Once you have identified differences, you can evaluate them and judge the film’s fidelity: how loyal it is to the book’s plot, characters, and themes. Ask: does this change strengthen or weaken the story’s theme? Does it make a character more or less believable? Does the film find a creative equivalent for what the book does in prose? A good evaluative opinion is specific: it names an element, identifies the change, and explains the effect.
In a fictional novel, the protagonist keeps a journal. In the film adaptation, the journal is removed.
How might a reader evaluate this change?
This evaluation is specific: it names the change (removing the journal), explains what is lost (access to inner conflict), notes the film’s alternative (close-up shots), and justifies its position with evidence.
Words to know
adaptation
A version of a story changed for a new medium, like film.
e.g. The film adaptation cut three subplots.
plot
The sequence of events in a story.
e.g. The plot of the book and film differed near the end.
character
A person or being who acts in the story.
e.g. One character was missing from the film.
setting
The time and place where a story unfolds.
e.g. The film’s setting moved the action to a city.
Venn diagram
A diagram of two overlapping circles used to compare and contrast.
e.g. They placed shared traits in the Venn diagram’s middle.
justify
To support an opinion with reasons and evidence.
e.g. She justified her preference with two specific scenes.
Comparison tip: before watching the film, make brief notes on three elements you remember clearly from the book — a character’s personality, a key scene, and the ending. Use these as anchor points when you compare. Small differences often reveal big interpretive choices.
