The Grey Man

Six (Ryan Gosling) is the last of the CIA's Grey Men, former prisoners recruited and trained as 100% deniable assassins. When his latest mission goes awry he finds himself on the run from the agency that made him what he is.

Lamb

Icelandic farmers Maria (Noomi Rapace) and Ingvar (Hilmir Snær Guðnason) live a quiet and somber life in their remote homestead.

At Christmas, one of their ewes gives birth to a very special lamb and the two adopt it as their own.

No good will come of this.

CW: animal births

Full Metal Jacket

We follow a group of recruits to the US Marine Corps from entry through to fighting in the ruined towns and cities of Vietnam.

CW: lots of 1960s racist, sexist, homophobic, xenophobic language but the real horror is the dehumanising effect of war

Taxi Driver

In 1970s New York at the height of its seediness, insomniac, probably traumatised Marine Corps veteran Travis Bickle (Robert DeNiro) works the night shift driving a taxi. He witnesses the worst the city has to offer and wants it all to just get washed away one day, never to be seen again. He looks down on those around him even though he's just part of that world.

Lacking human connection, Travis develops a stalkery obsession with political campaigner Betsy (Cybil Shepherd) and amazingly manages to convince her to spend time with him. However she's clearly his cultural and intellectual superior and occasionally mocks him. After a terrible faux-pas she rejects him, setting him on a path to violent retribution.

CW: full spectrum 1970s seediness including paedophilia, racism, sexism, homophobia etc.
