Big Finish has announced that Torchwood will be back for a brand new series of audio adventures with Torchwood: Aliens Among Us...

The new series, revealed at the DWAS convention The Capitol II, will follow the events of Miracle Day, and will see the Torchwood team reunited. Captain Jack, Gwen and Rhys will be joined by new characters co-created and overseen by series creator Russell T Davies.

In this series, Captain Jack and Gwen Cooper have restarted Torchwood in Cardiff, home of the original Torchwood Three. But it's in a very different Cardiff. Something terrible's happened to the city. With every day getting darker, will Torchwood need to adopt a whole new approach?

Producer of Torchwood Season 5, James Goss, talked about the new Torchwood team and Russell T Davies’ involvement. This new series of Torchwood will be released in three boxsets, the first being out in August. Torchwood Series 5.2 will follow in October and 5.3 will complete the season in the new year.

Press reaction to this week's Doctor Who episode Knock Knock is mixed. While many reviewers disagree about the strength of the writing, most are agreed on the quality of the performances in the story.

The Telegraph thought the acting plaudits belonged to the main guest star. "David Suchet playing the Landlord was brilliant casting. Just menacing enough as he mysteriously appeared without warning, smiling evilly in corners. Grey-haired and brown-suited, Suchet even looked ghostly. Never before has a tuning fork seemed so sinister."

Radio Times relished the creepy nature of the episode, but was disappointed by the ending. "For the first 35 minutes or so of Knock Knock I’m enthralled. Unfortunately, it showed signs of collapsing like a soufflé during the denouement...... I’d have been far happier with an unhappy ending. And yet I’m dismayed that, as the house crumbles, Bill loses all her knick-knacks, including the treasured photos of her mum that the Doctor sourced for her only weeks ago.

Den of Geek takes the opposite view, preferring the last third of the story. "Appreciating that some aren’t happy when Doctor Who goes emotional in its story wrap-ups, the fact that David Suchet’s mysterious landlord is actually the son of the woman we assumed to be his daughter is a very well earned, impactful piece of storytelling. I like that it works as a twist, but mostly, that it works because it adds real tenderness to the story."

The Mirror felt the episode to be the weekest of the season so far, feeling the character of The landlord was confusing. "Rather than allowing the bad guy of the week to be wonderfully creepy, he gets a 180 in the last few minutes to try and make us sympathise with him. But again, you can’t go killer madman to poor boy trying to save his mother in 3 minutes flat. Frankly, if you bag an actor of such calibre you can't waste him on a character that chops and changes."

Games Radar felt the writing was disapointing after last week's triumph. "The flat story is elevated slightly by David Suchet’s masterful acting, and Bill coming out as bluntly as possible does provide an air-punch moment. But even those stand-outs can’t redeem the overall limp writing. "

Flickering Myth disagreed. "When Doctor Who aims to frighten you, it really knows where those dark corners are in your mind, where you keep those little things you don’t like in your own cozy home, and brings them into light for everyone to see and to watch you leap two foot off your sofa. In this latest episode of Series 10, written by Mike Bartlett, you’re seriously going to be considering screwing down that creaking floorboard outside your bathroom by the end of it."

Carter Matt also enjoyed the story. "What was so fascinating about this story was that the more we saw of it, the more apparent that it became that this was not a story about good and evil; it was a story in some ways about a sacrifice, and what a father was able to do for his daughter. "

AV Club appreciated the style of the story. "Rarely does Doctor Who embrace another genre as completely as the first 30 minutes of “Knock Knock” does. For the first two thirds of its running time, tonight’s episode is a horror movie, with all the customary trappings. There’s the spooky haunted house with the still spookier landlord. There’s a bunch of thinly sketched young people who are all possibly idiots. There are loud noises and eerie music and windows and doors shutting all by themselves. If anything, it’s all a bit old-fashioned, in the best possible way."

Ars Technica praised the effects in the episode. "The storyline is a bit horror-by-numbers as one by one Bill's pals are bumped off by the alien woodlice. The on-screen effect is pretty grim, if thoroughly gripping, and reminds me of the carnivorous scarabs in The Mummy."

Digital Spy also felt the effects were well realised. "The episode is admirably daring when it comes to its scares, throwing up some genuinely disturbing visuals, particularly the sight of a pained Pavel (Bart Suavek) half-eaten by the house, and of a screaming Harry (Colin Ryan) being eaten alive by the Dryads."

Screen Rant looked at the themes behind the current series. "Weighing the life of one against the lives of many has been a recurring theme during Capaldi’s tenure as the Doctor, and with ‘Knock Knock’ the series places the Time Lord in a more intimate situation, almost like it’s a test to see what he’ll do when faced with a group of twentysomethings trapped in what appears to be a haunted house"

Nerdist also picked up the horror in the story. "One of the show’s main goals since the beginning was to scare people senseless. Monstrous aliens are part and parcel of the show’s success, and that often sends people “behind the sofa.” This week’s “Knock Knock” fits right in that genre…for good and ill."

IGN returned to the relationship between The Doctor and his new companion. "I enjoyed “Knock Knock” from the get-go, particularly -- as usual -- due to the Doctor’s interactions with Bill, as we see her here slightly embarrassed by the weird old fella around her new friends. This is her granddad helping her move, she insists, but no, he says, he’s her dad. Can’t we at least say I’m the dad?"

Doctor Who - Knock Knock had an overnight viewing audience of 4.32 million viewers, a share of 24.9% of the total TV audience, according to unofficial figures. Doctor Who increased its audience by half a million from the previous week.

Top for the day was once more the ITV variety show Britain's Got Talent with 9.35 million viewers. Doctor Who was top for BBC One for the evening, with Pointless Celebrities getting 4.20 million watching, while Casualty managed 4.02 million.

Former Doctor Who producer Philip Hinchcliffe has been honoured with an award for outstanding contribution to the programme, presented by the Doctor Who Appreciation Society, or DWAS.

Hinchcliffe was the producer of Doctor Who from 1975-1977, one of its most fondly remembered periods. He was producer while the DWAS was being formed by a group of students, anxious to discuss and celebrate their favourite programme.

Presenting the award at the DWAS convention, The Capitol, being held in Crawley, one of the founder members of the society, Jeremy Bentham spoke of the support the fledgling organisation had received from the Hinchcliffe and the BBC. That support helped enable the group to grow from a small college based club, to become a national society approved by the BBC. The group had been invited to visit the production office to meet the team and to discusses the series. A mention in the Radio Times in the listing for Masque of Mandragora, brought huge numbers of new membership applications.

Accepting the award Philip Hinchcliffe said.Script writer Bob Baker was also presented with an award for outstanding contribution to Doctor Who for his work on the series, in particular his creation of K-9, who celebrates his 40th Anniversary later this year.

The new design for The Doctor's favourite tin dog, K-9 has been revealed at the DWAS convention being held this weekend in Sussex.

The robot dog will feature in a new movie, TimeQuake, due to be released next year.

The new design was unveiled by the Robot's creator, Bob Baker and by Paul Tams, the producer of the upcoming film and one of the men behind the Australian TV series K-9

The new film will see the robot dog battle against Omega, another character created by Bob Baker along with his late partner Dave Martin.

The new design was created using a 3D printer using the films CGI model as a blueprint. It was unveiled at the Doctor Who Appreciation Society Event, The Capitol, being held in Crawley, West Sussex, this weekend.

A special 3D sound mix of this week’s episode makes it feel as if you’re part of the action, according to a group of Welsh students.

Speaking at an exclusive screening of the binaural audio edition of episode four, Knock Knock, the students called it a great experience, saying the enhanced version sounds as if at any minute the monsters could be coming after you.

The enhanced binaural audio episode will be available on BBC iPlayer immediately after the adventure premieres on BBC One and BBC One HD from 8.10pm on Saturday, 6 May. Viewers can find it by searching Doctor Who Enhanced on BBC iPlayer or visiting: www.bbc.co.uk/doctorwhoenhanced

The binaural edition creates a 3D surround soundscape for anyone wearing headphones, placing the audience at the heart of the action while the bumps, scrapes, shrieks and screams echo around them as if they were actually there. To create the enhanced version, the team used new software developed by BBC Research & Development to artificially mimic the subtle effect the shape of the viewer’s head and ears have on what they hear. This lets sound engineers give the impression of specific sounds like the creaks and groans of the old house in Knock Knock being in front, behind, or all around viewers.

Brian Minchin, executive producer, Doctor Who, said: Catherine Robinson, audio supervisor at BBC Wales, said:

Nerd Block, in association with BBC Worldwide, is launching the Doctor Who Official Block.
