The force really will be with sci-fi fans this weekend at a convention in South Yorkshire - Star Wars legend Dave Prowse, who played Darth Vader, is part of the invasion.
He is a late addition to join a galaxy of sci-fi stars, including two Doctor Who favourites, who will beam into Doncaster this for a feast of out of this world fun.
Digi-Con, which describes itself as ‘the ultimate geek weekend’ will descend on Doncaster Racecourse on Saturday and Sunday, January 10 and 11.
Guests include a host of stars of stage and screen as well as a string of other entertainments and attractions.
Leading the charge will be Doctor Who stars Peter Davison and Paul McGann, who played the fifth and eight incarnations of the much loved television Time Lord, respectively.
Dave Prowse, who played Darth Vader in the original series of Star Wars films, is returning following an appearance at a similar sci-fi style event a few weeks ago.
Also attending is Frazer Hines, who starred in 117 episodes of Doctor Who as companion Jamie McCrimmon before going on to star as Joe Sugden in ITV farming soap Emmerdale Farm.
A host of other actors, writers, illustrators, authors, musicians will also be in attendance for photo shoots, talks, autograph opportunities and more.
A spokesman said: “Digi-Con is a new weekend long convention. It will bring a variety of special guests, panels, shows and over 100 trader tables to appease your geeky needs!”
Other attractions will include a life size mock-up of The Simpsons sofa, the van from hit 1980s US action series The A-Team, Knight Rider car Kitt, Daleks, Cars favourite Lightning McQueen as well as a Tardis from Doctor Who, attractions from the Ghostbusters franchise and a Battlestar Galactica
McGann starred as Doctor Who in the 1996 TV film but did not appear in a series of the sci-fi classic, although he did record a series of audio adventures as the character.
He came to prominence for his appearance in 1986 BBC drama The Monocled Mutineer and went on to appear in cult comedy Withnail And I where he appeared alongside Richard E Grant.
Davison starred as the fifth doctor between 1982-84 and has also enjoyed a long and successful career in film and television.
Digi-Con opens at 10am – 9am for VIP ticket holders – and is open until 8pm on both Saturday and Sunday.
The event is open to all ages but under 12s must be accompanied by an adult over the age of 16.
