Compare how a story is told in written form versus film form, identifying what changes and what stays the same, and why.
Books and films tell stories with different tools. A book can put you directly inside a character's thoughts using narration (this connects back to point of view, Week 6); a film usually cannot show thoughts directly, so it relies on actors' expressions, music, and camera choices instead to convey the same feeling.
When a story moves from page to screen, some changes are simply required by the different medium, a film cannot include pages of inner thought, and other changes are choices, cutting a subplot or changing an ending, that a filmmaker makes on purpose. Good analysis tells these two kinds of change apart.
Mastery looks like: They distinguish required medium changes from deliberate creative choices when comparing a book to its film version, with specific examples.
Common stumbles: Assuming every difference between a book and film is either a mistake or automatically justified, rather than analyzing WHY each change happened.
