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.

Men In Black 3 (2012, dir. Barry Sonnenfeld)

Agent J has to travel back to 1969 and team up with the younger Agent K to defeat a time-travelling villain. Superior third instalment, building on fan affection for our alien-fighting duo, and working in terms of comedy, pathos and action. The best of the series.

Time Trap (2017, dir. Ben Foster & Mark Dennis)

Searching for their college professor, a group of students find themselves lost in a cave system where spacetime is distorted. Solid-enough low-budget SF/horror that grounds itself with location shooting. Some variable scripting and acting, perhaps inevitably, but the film doesn’t overwork its premise.

Triangle (2009, dir. Christopher Smith)

A single mother becomes trapped in a temporal loop on an abandoned liner. A smart little thriller that plays fair by its premise, doesn’t over-explain, and takes a rigorous approach to its plotting. A couple of genuinely nasty ideas embedded as well.

Happy Death Day 2U (2019, dir. Christopher Landon)

Tree finds out the reason for her time loop; but she’s trapped inside it again. Decent SF-tinged sequel to the Groundhog Day-aping original, this time with an expanded cast and a greater focus on humour throughout. No classic, but still fun and inventive enough to make Part 3 a welcome prospect.

Safety Not Guaranteed (2012, dir. Colin Trevorrow)

A reporter and two interns investigate a classified advert promising time travel. Lo-fi comedy that doesn’t outstay its welcome. Charming enough, with just a hint of sci-fi, and with fine performances all round.
