Colin Baker and Frazer Hines have been added to the list of star names appearing at the BritSciFi Weekend taking place at the National Space Centre in Leicester tomorrow and Sunday.
The event is a celebration of TV programmes such as Doctor Who, Blake's 7, Red Dwarf, and Thunderbirds.
As previously reported, other guests with a Doctor Who connection appearing at the event are visual effects designer Mat Irvine and actors Shane Rimmer and David Graham (although the centre is emphasising Rimmer and Graham's Thunderbirds link).
Daleks will also be in attendance, as will the Hyde Fundraisers voluntary group, who will be creating a Doctor Who walk-through experience in the venue's Challenger Centre, with creepy encounters featuring some monstrous creatures from Doctor Who. It will feature light, smoke, and sound effects not suitable for very young children. Tickets for the encounter are available on a first-come, first-served basis for performances each day.
In addition, David J Howe, the co-founder and editorial director of Telos Publishing, who has written a number of books about Doctor Who and owns one of the largest collections of Doctor Who merchandise in the world, will be there.
All the money from the BritSciFi weekend will go to charity, including Children In Need.
(NB: Attendees should ensure that the guests they want to see will be there on the day that they wish to go, as not all the guests will be there on both days.)
