Alien: The Director’s Cut (1979/2003, dir. Ridley Scott)

The 2003 re-edit (actually shorter than the 1979 original version) reinstates some scenes, clarifies some plot and character points and removes others (Ash is no longer a recent crew addition, and so the conspiracy element is toned down). By no means essential, but a chance to marvel again at this still-influential movie.

Contact (1997, dir. Robert Zemeckis)

A young astrophysicist decodes a signal from an alien intelligence. Good-hearted SF thriller from the Carl Sagan novel held together by fine performances and a positive outlook on space.

Alien (1979, dir. Ridley Scott)

A commercial space vehicle answers a distress call. Perhaps showing its age in some of its choices, nevertheless Alien is a storming piece of cinema, is outstandingly designed, directed and acted, and remains both relevant and influential 40 years on. A classic.
