A STAR Trek convention in London has said it has broken the record for the largest-ever gathering of people in costumes from the sci-fi franchise.

Destination Star Trek London, which is taking place at ExCel, claims 1,083 so-called Trekkies dressed up as characters from the TV series and films, beating the previous record set by 1,040 people at the annual Star Trek convention in Las Vegas two months ago.

If the feat was to be confirmed by Guinness World Records, the convention would score a second record in a matter of days for the convention after it hosted the UK’s first-ever Klingon marriage ceremony. Swedish couple Jossie Sockertopp and Sonnie Gustavsson got hitched on Friday in full-Klingon attire in a service featuring the alien race’s guttural language.

Most of the people taking part in today’s world record bid donned the brightly coloured uniforms of the Starfleet, but one fan made those dressing up as Vulcans or Romulans look tame when he arrived as a mugato, a yeti-like creature with a giant horn protruding from the top of its head.

‘It looks silly, it’s just a gorilla suit painted white with horns on it. It’s very, very hot. In fact, I was on the verge of collapse when a very kind person gave me a bottle of water because I dehydrated quite badly,’ said Mark Whitfield.

Dawn Harris, 26, created her own Orion slave girl costume and painted herself green as well. She likened edge-of-space skydiver Felix Baumgartner’s achievements to the enduring appeal of Star Trek, which spawned six TV series and 11 films.

‘There just hasn’t been a convention in the UK for so long,’ she said. ‘So I think everyone wants to be involved in everything as much as they can. Everybody saw that guy jump out of a plane in space so people are drawn to things like that.’

Her fiancé Ryan Croft added of the world record bid: ‘Nerds like achieving missions. We’ve been set a quest and it must be achieved.’

More than 17,000 Star Trek fans are thought to have descended on ExCel for the convention. On Friday the five actors who played the series’ five captains appeared on stage for the first time.

William Shatner, 81, who played Captain James T Kirk in the original series, said: ‘It’s an accumulation of a lot of work and a lot of people travelling from all over the world here. It’s sort of monumental in its worth.’
