Sci-fi fans are a passionate bunch, and this was evident last Sunday during the Norwich Sci-Fi and Film Convention on Sunday when rival fans clashed, prompting a visit by local police to calm things down.
The BBC reports that one member of a Doctor Who club, Jim Poole, visited the University of East Anglia to collect autographs from Who actors Graham Cole and Jeremy Bulloch - there for a Star Wars convention. Arriving at the venue, Poole received verbal abuse from a Norwich Star Wars Club member and subsequently called the police.
"I was put in a police car. We were both interviewed by the police and told to stay away from each other," he said.
Mr Poole said two other members of his club, one dressed as the 10th Doctor and the other as Judge Dredd, had waited outside the venue.
"This wasn't a fight between Star Wars fans and Doctor Who fans with lightsabers and sonic screwdrivers drawn," he said.
"It's a bit sad and pathetic. We're all in the same boat. We're not in competition."
Thankfully, it seems that balance has been restored to the force and time streams have been re-aligned. Apparently, both clubs were planning to meet up to resolve their differences.
Have you ever experienced any kind of rivalry like this? Shouldn't sci-fi fans all be in it together?
