The huge fire at the Warner Bros Studios was on the set of new comedy show Avenue 5, it has been confirmed.

Firefighters were called to the film studios in Leavesden at 11.30pm on Wednesday (July 10) but the call was escalated and 13 more fire crews from across Hertfordshire attended to help put out the blaze.

Fortunately, there were no reports of any injuries and the set was not being used at the time.

This evening (Thursday, July 11), producer of Avenue 5, series creator Armando Iannucci, said: “On behalf of the entire cast and crew of Avenue 5, I want to thank the firefighters who’ve been working tirelessly throughout the night to keep everyone and everything safe.

"I send my thoughts to the residents in the area who were disturbed by the night’s events. It was a beautiful set but everyone’s safety is the main priority. The season is near completion and everyone is determined to carry on."

Avenue 5 is an upcoming American science fiction comedy television series created by The Thick of It producer Armando Iannucci that is set to premiere on HBO.

It stars Blackadder and House star Hugh Laurie as Ryan Clark, captain of the Avenue 5 spaceship.

It is believed the fire at the studios has always been “under control” but three more crews arrived this morning while crews have been pumping water from a nearby canal in Hunton Bridge to help deal with the fire.

Hunton Hill Bridge and South Way have both been reopened having been shut for most of the day to allow firefighters to connect a hose between the canal and the studios.

At 2.50pm, Hertfordshire County Council confirmed the fire was out but several emergency vehicles remain on site.
