At 10pm on Saturday October 29, hundreds of zombies will perform the iconic routine at exactly the same time as thousands across the world in cities such as Hong Kong, Melbourne, Kuala Lumpur and in at least one city in every state in the USA.
Getwestlondon went behind the scenes to enjoy the final stages of rehearsal of the 10th annual 'Thrill The World'.
Organiser, Boogie, is expecting this year's London performance to be bigger and better than before and said: "We are hoping to beat our last years number of 267.
"I try and do little bit more each year so its raising the game a bit."
Zombies travel from across the world to take part in the event.
In the past, the London performance has attracted dancers from as far away as China and Austrailia.
Take a look at the event from 2008, with performances from across the world:
If you were thinking this event was just about Halloween, then think again.
'Thrill the World' also aims to raise money for charity.
Barbara Dagg travelled from Ireland for a previous event in London and raised £265 for the NSPCC.
"I had a blast," she said.
"It was all great fun, well worth the journey from Dublin, and everyone I met there was lovely."
This year the dance is supporting a number of charities including the NSPCC, SOS Children's Villages and Michael Jackson's Legacy.
Boogie said those coming to the event on Saturday can expect "lots of fun, lots of laughter, lots of great people, teamwork."
"The whole event is about the world coming together and dancing at the same time," she said.
She said the dance is for absolutely anybody and everybody and its all about "bringing people together" through dance and breaking down barriers.
So if you've got two left feet, or you have only just got "dad dancing" down to a fine art, then you do not need to worry.
If you want to join the Halloween fun, there's still time to sign up and learn to dance like a zombie.
