Guillermo del Toro has laid down markers as a wizard of the fantastical with such previous works as Pan’s Labyrinth and Crimson Peak (though we’ll skate nimbly around Pacific Rim), and now he has brought it all back home with The Shape of Water, as its 13 Academy Award nominations might suggest.

It’s not 1982 any more, but there’s still some disagreement between Ridley Scott and Harrison Ford about whether Rick Deckard was or was not a replicant. Thirty-five years on, Dennis Villeneuve’s belated sequel to Blade Runner may trigger another insoluble debate: is Blade Runner 2049 the real thing or not? A mythic masterpiece in the key of orange, or a snoozathon bloated with soulless self-regard?

Playwright Alan Ayckbourn basically comes in two flavours: suburban comedies of embarrassment and sci-fi fantasies. His latest, The Divide, which premiered at the Edinburgh International Festival last year in a two-part six-hour version, has been now been trimmed down to a single very long evening for its short stay at the Old Vic in London.

Fans of Luther will be familiar with writer Neil Cross’s fondness for hideous violence, shocking plot-twists and macabre humour, as well as characterful London locations, and happily they’re all present and correct in this new sci-fi thriller.

And so, with one last speech on the importance of kindness, Peter Capaldi and Steven Moffat bid farewell to the TARDIS. In their final Doctor Who episode, Twice Upon a Time subverted expectations with a small, sweet adventure which valued character above plot.

It’s impossible to view The Last Jedi independently from its predecessors. It’s the second instalment of the third trilogy of cinema’s greatest space opera. And it’s very much a product of what came before, but not in the way you might expect.

Director Richard Jones watched all 156 episodes of The Twilight Zone as research for this Almeida production.

The Incredible Shrinking Man starts innocently with a young couple bantering on a small boat off the California coast. Before what looks like an atomic mushroom cloud wafts towards the unfortunate Scott Carey, lightly coating him in glittery fallout. Six months later, Carey seems to be getting smaller. Initially it’s little more than an irritation.

To quote the genius sax player Dexter Gordon, "In nuclear war, all men are cremated equal" – or in this case, all adorable couples will burn as one. Anthony Edwards plays Harry, a not-so-genius trombone player who one sunny afternoon in Los Angeles meets Julie (Mare Cunningham), a waitress enjoying her afternoon off. They flirt amid the remains of extinct animals once dug out of the prehistoric La Brea Tar Pits in downtown LA.

Ridley Scott’s original Blade Runner from 1982 stands as an all-time sci-fi classic, so anybody trying to make a sequel (even 35 years later) needs galaxy-sized vision, an army of high-powered collaborators and balls of steel. Is director Denis Villeneuve the man for the job?
