The hateful eight solidified my fan-dom of Tarantino.
The scene were John Ruth (Kurt Russell) smashes the guitar... Kurt forgot to wait for the director to say "cut" so they could switch out the real priceless 18th century relic on loan from a museum with a fake for him to smash. Daisy's reaction (Jennifer Jason) was not her acting, it was her real reaction trying to stop Kurt from smashing the real guitar!
Quote: It was a priceless, irreplaceable artifact from the Martin Museum... As a result of the incident, the company will no longer loan guitars to movies under any circumstances. -Dick Boak, director of the Martin Guitar Museum
