A triple explosion and fire near the O2 Arena was described as a “thunderclap” on Saturday evening.
Several blasts were heard from around 7.30pm in Dock Road, Silvertown, and thick smoke was seen billowing over the event venue.
A van was destroyed while most of a car and a lorry were damaged in the huge blaze, the London Fire Brigade said.
It was later confirmed that it was a controlled explosion that was released on a film set as part of an unnamed upcoming production.
However, the fire spread out of control and led to 25 firefighters being called to the scene.
The effect was enough to leave residents of North Greenwich and the Isle of Dogs feeling rattled.

One witness described seeing “the biggest explosion they’ve ever seen” while they watched in shock from their balcony, as emergency services arrived at the scene shortly before 8pm.
One onlooker described hearing a “triple explosion” near the Silvertown Tunnel.
He said: “I think it was a BBC World truck. We noticed it around lunchtime as it was unusually in the area. Then 20 mins ago we felt and heard the three strong explosions.”
Another witness told the Standard how the explosions “shook the entire neighbourhood” and explained a BBC truck had been positioned at the site for around two weeks.
Four fire engines and around 25 firefighters tackled the fire at an open-air yard on Dock Road in Silvertown, on the other side of the River Thames from The O2.

Just witnessed the biggest explosion I've ever seen whilst I was on my balcony. Biggest flames and loudest bangs I've ever seen and heard. Police boats, helicopter and can see loads of blue lights headed that direction. Hoping it isn't a residential building. pic.twitter.com/XCXUJAJClL

Ryan O'Sullivan, 44, who lives in a flat opposite where the incident happened, said it sounded like an “earthquake”.
The business manager told the MailOnline: “We could have been warned there was going to be a controlled explosion.
“I thought it was a bomb. My flat was shaking. It was a huge shock. The smoke went right across the river. It was insane.
“I just thought the worst.”
