A fire broke out at Warner Bros’ studio in Leavesden, Hertfordshire on Wednesday and it took firefighters more than 15 hours to tackle the blaze.
The set was not in use when the fire broke out on Wednesday night. No injury was reported.
All eight Harry Potter films, James Bond, Fast and Furious and the Mission Impossible franchises have filmed at the studios.
A spokesman for Warner Bros thanked the firefighters who have "been working tirelessly throughout the night" and sent his "thoughts to the residents in the area who were disturbed by the night's events".
