Few books make a better adaptation study than The Princess Bride. Goldman wrote the novel in 1973 and later wrote the screenplay for the 1987 film directed by Rob Reiner, so the same author made choices in two different media. That gives teachers something rare: a comparison where the differences are deliberate.

The film keeps the adventure and trims much of what makes the book strange. The frame becomes a grandfather reading to a sick grandson instead of Goldman's elaborate claim about an abridged classic. Students who notice this can write about how each version treats its audience.

The typical comparison essay, though, is a list. In the book Buttercup does this, in the movie she does that, and the essay ends when the list does. Nothing in a list requires a thesis.

To get better essays, change the question. Instead of asking what is different, ask why a choice was made and what it costs or gains. That one shift turns observation into argument.

What the rubric should reward

A comparison rubric should reward purpose first. A student who picks two or three meaningful differences and explains them will beat a student who catalogs ten. Build that preference into the scoring so students see it before they write.

• A thesis that makes a claim about the adaptation, not just a statement that the two versions differ
• Specific scenes or details from both the book and the film, not general impressions
• Analysis of how the medium shapes the choice, such as pacing, visuals, or spoken dialogue
• Fair treatment of both versions instead of declaring one better without reasons
• Clear organization by idea rather than by whichever version the student remembers first

Common problems you will see

The first is the preference essay, where the student announces which version is better and stops. Preference is fine as a starting point, but it needs criteria. Ask what standard the student is using to judge.

The second is uneven evidence. Students often remember the film vividly and the book vaguely, so their book paragraphs are thin. If you see that pattern, it is worth a quick conversation about whether the reading was finished.

Feedback that improves comparison writing

Try comments that ask for the missing link, such as what the film gains by cutting this scene and what the reader loses. These questions point students toward the analytical move without giving them the answer. They also make revision faster, because the student knows exactly what is missing.

When you have a full set to get through, rubric-driven AI tools such as GraideMind can produce first-pass comments tied to each row, which you can adjust before returning papers. That keeps your feedback consistent across sections. You spend your energy on the borderline essays.

A note on fairness

Some students have seen the film many times and never opened the book, and others are the reverse. A rubric that requires evidence from both keeps the playing field level. It also nudges everyone toward doing the reading.

Consider letting students choose their two focal differences from a short list you provide. That reduces the risk of everyone writing about the same famous scene, and it makes grading less repetitive. Your patience for essay number forty will thank you.
