THE PLOTLINES AND PEOPLE MIGHT BE GALAXIES APART, but when Dr Who fans clash with Star Wars followers in the real world, the results can be handbags at dawn.
Sometimes galaxies collide and while this might not cause a black hole, it could contribute to a black eye or fat lip.
East Anglia learned that yesterday when people dressed up like characters from the hokey space and time shows took it upon themselves to start a glaring, staring, name calling argy-bargy at the fourth Norwich Sci-Fi and Film Convention at the University of East Anglia.
Jim Poole, treasurer for the Norwich Sci-Fi Club said that he visited the event with a friend, adding that both of them were dressed in Dr Who regalia. On arriving they were greeted with insults, and decided to hop inside the TARDIS and call the rather more down to earth police.
According to the police, no sonic screwdrivers or lightsabers were used to hurt anyone.
"After a lengthy investigation, talking to witnesses and reviewing good CCTV footage, it was confirmed that there was no assault," a spokesperson for Norfolk Police told the BBC. "The two rival groups were spoken to and advised to keep out of each other's way."
Since this is the Star Wars universe we cannot rule out the possibility of a special edition CCTV video in which Han doesn't shoot first, and some CGI explosions wipe the Dr Whovians off the conference floor.
That might come later. For now we have to console ourselves with the damp squib that is some name calling and some running away.
"This wasn't a fight between Star Wars fans and Doctor Who fans with lightsabres and sonic screwdrivers drawn," added Poole with the sort of thinking you might get from the Dr.
"It's a bit sad and pathetic. We're all in the same boat. We're not in competition. We'd like to extend the hand of friendship."
However, he added that the next convention is likely to be guarded in case of any trouble. They might as well stand down though, since apparently there is no fight in the East Anglian Star Wars gang.
"It's been blown up as if it was a fight. There was no fighting," said Dominic Warner, secretary of the Norwich Star Wars Club.
"It does sound comical. People that dress up in costume are labeled geeks and some people laugh at us, and this just makes it even more so." µ
