Photos captured by PA news agency photographer Owen Humphreys revealed a staged fire at the historic coastal castle, alongside a Second World War-era motorbike.
Harrison Ford reprised his role as the world’s most daring archaeologist at the age of 78, but it was not clear if Dr Jones was the one riding the motorbike.
The fiery spectacle sparked speculation that it was linked to yet another death-defying escape from the Nazis.
Bamburgh Castle was closed to the public for several days leading up to the filming, with Second World War vehicles spotted being delivered to the site.
Local residents were informed that filming would occur at night, with warnings about potential loud noises.

On Thursday evening into Friday morning, the crew staged a fire that illuminated the night sky.
Mr Humphreys said at the time: “They started to test the set around 9pm and filming went on to about 1am.
“They staged a fire and we could see a man on a motorbike going up to the castle – it could be a prison break scene, after all, this is Indiana Jones.
“It looked spectacular in the night sky with the backdrop of the famous castle.”
During breaks from filming, Ford was spotted cycling along the Northumberland coast and on Tyneside.
Earlier in the filming schedule, he had charmed a young fan in Grosmont, tipping his famous hat and joking that he was Indiana Jones’s stunt double.
Props for the film included tanks, a guard tower, and a steam train adorned in the colours of 1940s German railways. In a delightful twist, the Newcastle Dog and Cat Shelter embraced the excitement by naming a litter of four kittens Harrison, Ford, Indiana, and Jones.
