An "original work" is defined as either wholly original or derivative of a non-famous cultural product in another medium (e.g. an obscure novel turned into a film). Sequels, films in a cinematic universe (e.g. MCU), films based on a non-book famous cultural product (e.g. Barbie), do not count as an original work.
Films about a person or group are original if they do not rely on a previous work about that person. So Oppenheimer does not count (it is based on American Prometheus), whereas Bohemian Rhapsody (2018) counts as original, as it is about a famous person but originally written.
This question resolves by checking the films that makeup the top 10 grossing films in the US in 2024 on Box Office Mojo using calendar grosses (see here for 2023).
