It is the event to which science fiction fans from Norfolk and beyond have been boldly going since 2009.

And this year, a galaxy of stars will be helping to make a new-look Nor-Con the biggest and best yet.

The annual science fiction spectacular was missing from the calendar last year, but details have been announced for a revamped event in October at a larger venue and with the promise of even more for sci-fi fans to look forward to.

Award-winning actress Miriam Margoyles, who played Prof Sprout in Harry Potter and the Chamber of Secrets, is one star who has already agreed to appear at Nor-Con 6, which takes place at the Norfolk Showground Arena.

Others due to appear at the event, in October, include Andrew Lee Potts, who starred in ITV's Primeval alongside Great Yarmouth-born Hannah Spearritt, and Ian McNeice, who has been in a variety of TV shows and films including playing Winston Churchill in Doctor Who, and Bert in Doc Martin.

Mark Dean, director of Nor-Con Events Limited, said: 'We've had a year's break to restructure and rebrand. Due to demand we've moved to a larger venue at the Norfolk Showground, which will allow us to have more people, more exhibits and exhibits that will be able to move around like the Daleks and R2-D2s because we've got the space.'

As well as celebrities signing autographs and taking part in question and answer sessions, there will be exhibitions, demonstrations, trader stands as well as the Norwich Star Wars Club UK, comic artists and cosplay – 'costume play' – groups.

Mr Dean said: 'It will be the biggest one we've done – there will be something for everyone. It's not just about sci-fi, now it's TV, film and comics.'

As in previous years Nor-Con will be looking to help raise money for charity, with donations this year going to the Louise Hamilton Centre at the James Paget University Hospital in Gorleston.

While the event is still some time off, Mr Dean has urged traders who want to attend to get in touch.
