Film crews will be in the town at the weekend shooting scenes at the Cross Keys Bridge for the blockbuster The Golden Compass, starring Nicole Kidman and Daniel Craig.
Rumours that Sutton Bridge was to be the backdrop for scenes in either the latest Harry Potter instalment or the next James Bond film have been doing the rounds.
But publicist Susan Darcy has confirmed a secondary unit for The Golden Compass will film the bridge opening and closing as it allows a barge to sail through.
Workers were floating the dutch canal barge into the water at Fosdyke on Tuesday so it would be in place by the weekend.
When asked if the two stars will be in town Ms Darcy said she did not know what the full filming schedule contained.
She said: "We have a secondary unit in the area filming some shots which will be dropped into the main action.
"We have done some filming in Greenwich and have the main unit at Chatham and Nicole won't be back with us until November."
The Golden Compass is the first in a trilogy adapted from Philip Pullman's bestselling His Dark Materials series.
The film is written and directed by Chris Weisz, whose credits include About a Boy and Antz.
Lincolnshire Police have issued a notice to motorists warning of delays and road closures around the bridge but say diversions will be in place.
