It didn't happen a long time ago, or in a galaxy far, far away but a clash between Star Wars and Doctor Who fans at a Norwich convention did mean organisers had cause to 'use the force' when police were called to break up a row between the two groups of fans.
Trouble flared on Sunday at the fourth Norwich Sci-Fi and Film Convention at the University of East Anglia, which was organised by the Norwich Star Wars Club.
Police were called to the venue after members of Norwich Sci-Fi club arrived and were reportedly refused entry.
According to reports more than a dozen Doctor Who and Star Wars fans were involved in the confrontation which was allegedly sparked when a member of the Norwich Sci-Fi Club attempted to get an autograph from Doctor Who actor Graham Cole.
The row follows a long-running dispute between the two groups and the hosts had reportedly warned the rival Norwich Sci-Fi Club to stay away from the event after a number of comments were posted on Facebook.
Norfolk police confirmed that they had attended the scene and had spoken to both parties.
No arrests were made.
A police spokesman said: "After a lengthy investigation, talking to witnesses and reviewing good CCTV footage, it was confirmed that there was no assault," the spokesman said.
"The two rival groups were spoken to and advised to keep out of each other's way."
Dominic Warner, secretary of Norwich Star Wars Club, told the BBC: "It's been blown up as if it was a fight. There was no fighting."
"It does sound comical. People that dress up in costume are labelled geeks and some people laugh at us, and this just makes it even more so."
