How true is "based on a true story"?
Not very, necessarily. "Based on a true story" means real events inspired it — not that what you see happened. Films and memoirs regularly compress timelines, merge or invent characters and add scenes for drama. Nothing legally stops them; only documentaries and journalism are held to a factual standard.
"Based on a true story" is like a friend retelling a funny thing that happened at school — the main event is real, but by the fifth telling the dog is bigger and the teacher is angrier.
- Documentary / journalism
- Memoir — one person's own account
- "Based on a true story" — dramatised biopic

The sliding scale
Documentaries and journalism try to show events as they happened. Biopics and docudramas dramatise real people and events, often changing details for pace and emotion. "Inspired by true events" gives even more freedom. Memoirs are one person's account of their own life — true by their memory, and occasionally not true at all.
Common changes
Timelines get compressed so events fit a two-hour story. Several real people become one character. Private conversations are imagined. Sometimes whole events are invented — which matters most when the people involved are real and can't answer back.
Checking the facts
Look for what the real people or their families have said, and for historians' or journalists' fact-checks. The PixProofs below document where specific films and books crossed from dramatisation into fabrication.

HYPE OR REAL?
"Bohemian Rhapsody shows the real timeline of Freddie Mercury's HIV diagnosis."
The answer: Hype. The film places it before Live Aid in 1985; he was diagnosed in April 1987 and told his bandmates in 1989.

- Does "based on a true story" mean it's accurate?
- No. It means real events inspired it. Dialogue, timelines and even whole events can be changed or invented.
- Is a memoir always true?
- It's supposed to be the author's honest account, but memories are selective and some memoirs have been exposed as partly fabricated.
- What's the difference between a biopic and a documentary?
- A documentary aims to show real events and people as they were; a biopic dramatises a real life with actors, and usually takes creative liberties.
