Here are the best sci-fi and cult TV box sets on BritBox…

Blake's 7

All 52 episodes and four seasons of the cult British sci-fi show from the mind of Terry Nation are available to watch now.

In the third century of the second calendar, after the chaos of the intergalactic wars, a powerful dictatorship has risen to dynamic proportions and engulfed most of the populated worlds.

This is the story of one group of rebels, led by a man named Blake. His group is largely composed of escaped convicts, thieves and smugglers who are thrown together by chance.

Watched by over 10 million viewers at its peak at the end of the 1970s, the mix of space opera, robots, aliens and adventure made Blake’s 7 must-see TV.

The Avengers

BritBox has the two complete surviving episodes of the first season, plus the iconic Emma Peel & Tara King seasons starring Patrick MacNee, Diana Rigg & Linda Thorson as the incorrigible secret agents extraordinaire.

The original cult TV classic, it remains an enduring mix of mystery, style and espionage.

Doctor Who and the Daleks / Daleks’ Invasion Earth 2150 AD

The two big-screen spin-offs from the television series featuring the infamous Daleks and starring Peter Cushing as the Doctor.

Cushing’s Doctor - an eccentric inventor who invents a time machine in his back garden – veers away from the many TV incarnations of the character, but many fans of the British TV institution still love the movies.

One Million Years BC

This spectacular prehistoric adventure was promoted as Hammer’s 100th production and gave the world the iconic image of star Raquel Welch in a fur-lined bikini.

The highlight of the movie was the stop-motion dinosaurs that were subsequently added by legendary special effects animator Ray Harryhausen. The result was Hammer’s biggest commercial success, the most famous dinosaur epic until the release of Jurassic Park 26 years later.

The Man Who Fell to Earth

Nicolas Roeg directs this classic 70s sci-fi drama starring David Bowie as an alien who arrives on Earth in search of water to save his own dying planet.

Assuming the name Thomas Jerome Newton, he soon forms a lucrative partnership with patent attorney Oliver Farnsworth (Buck Henry) by creating revolutionary products. As their business develops into a hugely successful financial empire, Thomas plans to use the profits to build a ship that will return him to his home world. However, while he waits for his ship to be ready, he begins to fall prey to earthly pleasures and failings.

Survivors

All three seasons of Terry Nation's acclaimed BBC science fiction drama are on BritBox.

In the series, first shown between 1975 and 1977, 95% of the population have been wiped out by a freak plague, leaving the remaining survivors to rebuild civilisation.

The Prisoner

All 17 episodes of the groundbreaking television drama created by and starring Patrick McGoohan are available to watch on BritBox.

A former British secret agent is abducted and held captive in a strange coastal village while those who captured him try to discover the truth of why he suddenly resigned from his position. 

Sapphire & Steel

The complete collection featuring all six seasons and 34 episodes from the 1980s sci-fi series starring Joanna Lumley and David McCallum as Sapphire and Steel.

The mysterious agents are charged with protecting the universe from the malevolent forces of time with their uncanny powers.

Gerry Anderson collection

Every episode of popular science fiction series Space 1999, all 32 episodes of cult supermarionation series Thunderbirds, along with the three brand new episodes Thunderbirds: 1965 that were created for the show’s 50th anniversary and all 32 episodes of Captain Scarlet & The Mysterons are available to watch.
