Nearly 2,000 fans of all ages celebrated the 50th anniversary of Doctor Who at the National Space Centre.
Evil Daleks and Cybermen rubbed shoulders with five of the Doctor's companions as they signed autographs at the science fiction festival on Saturday.
The centre was packed with people dressed as characters from the series and fans had the opportunity to quiz backroom staff about the long-running TV show.
The five companions – Sophie Aldred, who played Ace, Louise Jameson (Leela), Frazer Hines (Jamie), Sarah Sutton (Nyssa) and Nicola Bryant (Peri) drew large lines of enthusiasts wanting to chat and get autographed pictures.
Ms Bryant, who starred alongside Colin Baker's Doctor from 1984 to 1986, said: "The atmosphere has been brilliant as we are celebrating the 50th anniversary of the Doctor in all his manifestations."
Visitor Danny O'Shea, 43, an engineer from Earl Shilton, said: "This is absolutely fantastic. I managed to have a chat with one of the people who made the Daleks and other villains work.
"Of course, I rate the Daleks as the best villains and Tom Baker was the best Doctor."
Rebecca Orton, 12, also from Earl Shilton, said: "I like David Tennant the best and the best villains were the reptilian Silurians."
People also had the chance to see a display of props including a Tardis and designs of Cybermen heads from different series.
Rebecca Page, 30 of Stoneygate said: "It is my first visit to this kind of event. It is great to see so much Doctor Who material."
The science of the Timelords was explained by Andrew Cartmel, a script editor on Doctor Who who oversaw the Sylvester McCoy era of the programme – 1987 to 1989.
Voice of the Daleks and Cybermen Nicholas Briggs gave people the chance to try out the device he uses on the show to create the perfect alien voice.
The day concluded with a parade of fans who had come dressed as characters from the series.
Lumbering undead with mutilated faces rubbed shoulders with horror fans sifting through the latest books, games and DVDs on Saturday.
It was the seventh annual zombie festival at the Phoenix cinema, where enthusiasts had the chance to view 13 hours of movies dedicated to the walking dead. Festival director Ed Thurlow, dressed in a blood-spattered evening suit and bow tie, said: "It was fantastic to see so many come along this year. It was our best year yet.
"Interest in zombies is on the increase and it is good to see people of all ages, although the children can't see the films."
People had the chance to talk to authors of zombie books Sean T Page, Adam Millard and Luke Duffy in the Arcade of the Dead.
The arcade also offered the chance to play treasured zombie conole games.
There was a best-dressed zombie competition and a short film competition with an audience vote deciding the best entry.
Professional zombie Steve Uden, 31, whose face was distorted by a huge gash in his cheek exposing his teeth, said: "I love this festival. It brings loads of people together from far and wide.
"I came here seven years ago and now I am a professional zombie, appearing in specialist events.
"People appear to like being scared by somebody standing next to them with their face in tatters."
