Doctor Who: The Day of the Doctor (2013, dir. Nick Hurran)

The Tenth and Eleventh Doctors face their past, personified. Splendid movie-length episode made in 3D and cinema-released to celebrate the show’s 50th anniversary. A witty time-travel adventure typical of its then-showrunner, made with both love and a keen sense of the show’s heritage. Recommended.

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.

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.
