Doctor Who: The Eternity Clock

The Eternity Clock game for Playstation 3 immerses players in the universe of Doctor Who across 600 years of history and the future. Players take on the roles of the Doctor and River Song as they travel across time and space to save the Earth, and time itself. In order to be successful, they must master the complexities of time travel through time-based gameplay - changes made in one time will impact another, creating multiple possibilities and challenging players to solve puzzles across the centuries.

Equipped with the Doctor’s “sonic screwdriver,” River’s “blaster” and other fantastic gadgets, players journey through four London time periods and a number of other-worldly locations in search of answers. With collaborative multiplayer capabilities, players can take part in the game simultaneously across different time periods, facing some of the most fearsome monsters including Silurians, Cybermen, Daleks and the Silence.

A Whole Scene Going is an exciting TV find. For Doctor Who fans there's a fascinating glimpse into the making of feature film Daleks - Invasion Earth: 2150 A.D., showing Peter Cushing as the Doctor on the set along with director Gordon Flemyng and lots of Daleks. For music-lovers there are priceless performances by classic British beat band the Spencer Davis Group as well as American singer/songwriter Judy Collins. Sixties pop shows were routinely shown live or wiped after transmission so it's great to find one that slipped past the eraser's magnet!

How this print came into existence or found its way to a Welsh village, we'll never know. However, one theory is that it could have been film-recorded by BBC Wales from the network feed down the line from London for transmission at a later date.

Doctor Who was not the primary draw for us in recovering this programme, but the content of the programme as a whole — the exciting period of popular culture it reflects and its place in the history of British television. Thankfully, after the collector discovered he had a unique TV recording he was keen to ensure it would be returned to the BBC archives, turning down silly money offers to deal instead with Kaleidoscope and the TDA.

When Elisabeth Sladen first appeared as plucky journalist Sarah Jane Smith in the 1973 Doctor Who story The Time Warrior, little did she know the character would become one of the most enduring and fondly remembered of the series' long history.

The years that followed saw Elisabeth traverse time and space alongside classic Doctors Jon Pertwee and Tom Baker, while a generation of children crouched behind the sofa, terrified but transfixed as their tea-time heroine found herself menaced by Daleks, dinosaurs, Cybermen, Egyptian mummies, actors in green bubble-wrap and even the Loch Ness Monster. By the time she quit the TARDIS in 1976, making front-page news, Elisabeth had become one of the most familiar faces of a TV golden age.

But you don't just walk away from Doctor Who. Elisabeth was asked to reprise her role many times, appearing in anniversary specials, an ill-fated 1981 spin-off with robotic sidekick K-9, radio plays, and for the BBC's Children in Need. She toured the weird, wide and wonderful world of Doctor Who fandom and became one of the series' all-time favourite companions. So when TV wunderkind Russell T Davies approached her to come back again, this time to a show backed by multi-million-pound budgets and garlanded with critical plaudits, how could she refuse?

This warm and witty autobiography, completed only months before Elisabeth died in April 2011, tells her remarkable story, from humble beginnings in post-war Liverpool, through an acclaimed theatrical career working alongside stage luminaries such as Alan Ayckbourn, to Coronation Street, Some Mothers Do 'Ave 'Em and the furthest reaches of the universe.

A unique insider's view of the world's longest-running science fiction series, and of British television yesterday and today, Elisabeth's memoir is funny, ridiculous, insightful and entertaining, and a fitting tribute to a woman who will be sadly missed by millions.
