The Best Episodes of Doctor Who Confidential

This BBC3 show took viewers behind the scenes between 2005 and 2011. Here are some of the best, although there are loads more fantastic episodes of Doctor Who Confidential.

Bringing Back the Doctor (Series 1, Episode 1): Learn how Doctor Who returned to TV screens in 2005.

The Daleks (Series 1, Episode 6): The Daleks are back! Well, one of them is anyway. For now…

The Dark Side (Series 1, Episode 7): An interesting look at our relationship with the media, focusing on The Long Game, but naturally also setting up Bad Wolf (not that we realised that when it aired).

The Last Battle (Series 1, Episode 13): A history of the Time Lords and the Daleks, yes, but most importantly, Christopher Eccleston’s final Confidential.

Script to Screen (Series 2, Episode 4): An inspiring journey, charting the full genesis of The Girl in the Fireplace, from draft to readthrough, filming to post-production.

The Writer’s Tale (Series 2, Episode 7): An in-depth chat with writer, Mark Gatiss (The Idiot’s Lantern).

You’ve Got the Look/ Religion, Myths and Legends (Series 2, Episodes 9 and 10): Confidential doesn’t do two-parters really, but this pair, accompanying The Impossible Planet/ The Satan Pit, is as perfect a thematic exploration as the show gives.

Finale (Series 2, Episode 14): Yes, there’s a lot of emotion as Billie Piper says goodbye to Doctor Who, but this is also quite a joyous episode, in the wake of the Daleks and Cybermen meeting.

Music and Monsters (Series 3, Episode 1): Only loosely linked to The Runaway Bride, this special actually delved into Doctor Who: A Celebration, the 2006 Children in Need concert.

Meet Martha Jones (Series 3, Episode 2): As Martha was such a breath of fresh air in Doctor Who, Freema Agyeman proves to be for Confidential.

Do You Remember the First Time? (Series 3, Episode 10): Sometimes called the best episode of Confidential ever, this is a love letter to the show as a whole (including 20th Century Who) and to BBC Television Centre, presented by David Tennant, who also makes his directorial debut.

Kylie Special (Series 4, Episode 1): Oh heck, Kylie Minogue on Doctor Who!

The Italian Job (Series 4, Episode 3): Charting the overseas adventures of the crew as they film The Fires of Pompeii.

Shadow Play (Series 4, Episode 9): The best thing Confidential does is make you think of the challenges and fun of production, specifically the bits that would never cross your mind otherwise — case in point: lighting in Silence in the Library, where shadows are so important…

Look Who’s Talking (Series 4, Episode 10): Behind the scenes on one of the most brilliant productions of Doctor Who, Midnight.

The Eleventh Doctor (Series 4 special): Confidential was so important, this episode aired on BBC1 and introduced the world to the Eleventh Doctor, Matt Smith.

Allons-y! (2009 Special): David Tennant’s last day on set (until the 50th and 60th) and Matt Smith’s first.

All About the Girl (Series 5, Episode 2): Looking at how the art and design departments created Starship UK in The Beast Below.

Eyes Wide Open (Series 5, Episode 4): Behind the scenes of The Time of Angels, but also looking at The Adventure Games.

Death in Venice (Series 5, Episode 6): Though The Vampires of Venice was filmed in Croatia, Confidential took writer, Toby Whithouse, to Venice itself to investigate the plague and vampiric reports with Venetian Historian, Francesco Da Mosto. An utterly fascinating episode.

Extra Time (Series 5, Episode 11): Series 5 of Confidential saw the show doing some really unusual and brilliant things, including, here, sending Karen Gillan to discuss the prime meridian, the nature of space-time, and time travel with Dr. Aderin-Pocock and Marek Kukula.

Alien Abduction/ Out of Time (Series 5, Episodes 12 and 13): All the challenges of filming the Series 5 finale (which also inspired by book, The Black Archive: The Pandorica Opens/ The Big Bang!).

Christmas Special 2010: Exploring A Christmas Carol, with the script readthrough proving a great jumping-off point.

My Sarah Jane: A Tribute to Elisabeth Sladen: This special, often considered part of Confidential, says a sad farewell to the one and only Elisabeth Sladen.

Breaking the Silence (Series 6, Episode 2): Filming in America!

Bigger on the Inside (Series 6, Episode 4): Neil Gaiman essentially presents an episode of Confidential.

Heartbreak Hotel (Series 6, Episode 11): This episode is particularly thought-provoking (with a discussion on the parallels between the Doctor and the Minotaur in The God Complex) and joyous, with Whithouse bringing his children on set to meet Matt Smith.

When Time Froze (Series 6, Episode 13): The last ever episode of Doctor Who Confidential.

The Best Episodes of Torchwood

Running for four seasons, Torchwood had great highs and depressing lows. Here’s what to want the best view of this Doctor Who spin-off. These are intended for adults only.

Everything Changes: Gwen Cooper is thrown into the grim and gritty world of Torchwood.

Ghost Machine: The team investigate a horrific murder as they’re seemingly thrown into the past.

Small Worlds: Sapphire and Steel creator, P. J. Hammond, gives us a terrifying take on fairies.

They Keep Killing Suzie: The team has to resurrect their departed comrade/enemy, Suzie Costello.

Out of Time: A displaced trio from the past have to find their ways in 2007, discovering that the future isn’t all it’s cracked up to be. The best of Series 1.

Captain Jack Harkness: Learn more about Jack Harkness. No, not that Jack Harkness.

Kiss Kiss, Bang Bang: Jack returns to Torchwood after the events of Doctor Who Series 3, but have things changed too much?

To the Last Man: The Torchwood team’s relationship with death is examined once more when they have to bring back a cryogenically frozen soldier from the First World War.

Reset: Martha Jones is temporarily recruited to the team.

From Out of the Rain: Two celluloid film stars escape into the real world.

Adrift: The best of Series 2. A haunting and emotional reminder that travels in time and space don’t always end well.

Fragments/ Exit Wounds: The Series 2 finale tears the team apart.

Children of Earth: This is technically Series 3 in its entirety, but you can’t separate individual episodes as it’s one five-part story — and the absolute best of Torchwood.

Miracle Day: The New World: Another season-long story, which is considerably less enjoyable than Children of Earth, but there are still some decent episodes, notably this opening part.

Miracle Day: The Categories of Life: The mid-point in Series 4 also gives us one of the most shocking and terrifying cliffhangers.

Miracle Day: The Blood Line: The season conclusion, in which we find out why no one on Earth (except Captain Jack) can die. Farewell, Torchwood.

The Best Episodes of The Sarah Jane Adventures

The best Doctor Who spin-off? There’s no question: it’s definitely The Sarah Jane Adventures. Each story is comprised of two episodes.

Eye of the Gorgon: A superb take on a classic myth, and tackling the subject of dementia in a compassionate and smart way.

Whatever Happened to Sarah Jane?: A deal with the Trickster means the Third and Fourth Doctor companion is erased.

The Lost Boy: The Slitheen are back, claiming Luke Smith, Sarah’s son, as their own.

The Last Sontaran: The first story of Series 2 picks up in the wake of The Sontaran Stratagem/ The Poison Sky.

Day of the Clown: Bradley Walsh proves absolutely terrifying in a tale that also introduces new character, Rani Chandra.

The Mark of the Berserker: Clyde Langer is one of the best characters in the Whoniverse; here, the focus is on him as he finds his estranged father, Paul.

The Temptation of Sarah Jane Smith: When Sarah finds herself in the past, she’s given the opportunity to meet her parents.

Enemy of the Bane: Notable for introducing the Black Archive… and bringing back Brigadier Alistair Gordon Lethbridge-Stewart!

Prisoner of the Judoon: Series 3 opens with the return of this memorable Doctor Who alien searching for a deadly fugitive on Earth.

The Mad Woman in the Attic: In the future, a young boy stumbles upon 13. Bannerman Road and meets the titular mad woman: a shattered Rani Chandra…

The Wedding of Sarah Jane Smith: David Tennant guests as the Tenth Doctor — the last thing he filmed as this incarnation of the Doctor until the 50th anniversary.

The Nightmare Man: Julian Bleach’s creepy character haunts Luke as he prepares to leave for university.

Death of the Doctor: Matt Smith guest stars as the Eleventh Doctor in this glorious tale which also brings back Jo Jones (née Grant)!

The Empty Planet: Rani and Clyde find themselves the last humans on Earth.

Lost in Time: A possible Time Lord scatters Sarah, Rani, and Clyde through different time periods.

The Curse of Clyde Langer: An exploration of homelessness, better than you’d find on adult TV, let alone CBBC. Probably the best SJA story ever.

The Man Who Never Was: And the story goes on…. forever.

The Best Episodes of Class

An underrated spin-off set at Coal Hill School was ultimately axed, but there’s plenty of goodness to be found in this eight-episode series.

For Tonight We Might Die: Peter Capaldi puts in a guest appearance as the Twelfth Doctor.

Nightvisiting: A spooky night-time visitor strengthens the character work in this ragtag team of students.

Detained: The class are held in a nightmarish detention.

The Metaphysical Engine, or What Quill Did: An episode focused on Catherine Kelly’s Miss Quill, probably the show’s best character.

The Lost: The series ends on a truly shocking cliffhanger which is yet to be picked up in the Doctor Who universe.

Special Mention

K9 & Company is also on BBC iPlayer (and is, of course, available on DVD too), and, as the first Doctor Who spin-off, is well worth a watch!

Tales of the TARDIS reunites Doctors and companions across six nostalgia-filled episodes, launching the so-called Whoniverse with new stories for Steven Taylor and Vicki, Jo Grant and Clyde Langer, and the Seventh Doctor and Ace, to name just a few.
