George Orwell's dystopian novel 1984 has two notable film adaptations: the first from 1956 and the second from 1984.

The 1956 film veers the most from the novel. It creates an alternate ending to the material. Instead of concluding with Winston and Julia being brainwashed by the authorities, the lovers are executed by firing squad. This ending allows Winston and Julia to remain faithful to one another as well as keep their revolutionary dignity intact, thus mitigating the tragedy of the book's conclusion. On the whole, this film version is also less graphic about sex and violence due to the film censorship rules in place at the time.

The 1984 film is noted for being closer to the original book, though there are still a few differences. This version creates a distinct hand salute for the Party, evoking Nazi Germany, and the Party's members also refer to one another as "brother" and "sister" rather than the more overtly Soviet "comrade" as in the novel. Otherwise, this version retains Orwell's bleak finale.
