It's been described as the country's friendliest convention, and the thousands of sci-fi fans who turned out to Nor-Con over the weekend certainly agreed.
On Saturday more than 2,000 enthusiasts flocked to the Norfolk Showground for the sixth year of the event, with many dressing up as their favourite characters.
Organiser Mark Dean said the day had been a raving success, especially as this was their first year in a larger venue.
'It's gone from being at the LCR at the UEA, which it outgrew, then a hotel near the airport, then we decided to take the leap of faith and go to the showground and it was fantastic,' he said.
But it wasn't just the people through the door who enjoyed themselves, as celebrities posed for photos and chatted with ticket-holders.
'We had Peter Davidson, from Dr Who, local girl Hannah Spearitt and Andrew Lee Potts from Primeval, and Ian McNice, Paul Blake and Norman Lovett. But we also had Danny John Jules, Cat from Red Dwarf,' said Mr Dean.
'We've been trying to get Danny for four years, and we finally got him to Norwich - we said we'd get him and we did.'
As well as the stars, supporters travelled from as far as the USA, Japan, and Denamrk, as well as within the UK.
'We actually had more people come from London than we did from Lowestoft,' said Mr Dean.
And visitors from aborad were kept happy with familiar food, including a Japanese street food stall in lieu of the food stalls you usually see at events.
This year the day, which is run by Nor-Con Events Ltd, will be donating around £2,000 to the Louise Hamilton Centre, which provides end-of-life hospice care in Gorleston.
