The event will feature 1750 marching troops from across the globe, as well as over 6000 volunteers, performers and key workers, plus 2500 members of the public.
There will also be a moving wedding cake blasting out Bollywood tracks, as well as a huge dragon and more monsters.
The Queen will also be represented as a 6m puppet depicting her as a young princess surrounded by puppet corgis.
Director David Zolkwer said: "This is very much a people's pageant — it's by and for the people.
"It's about ordinary people coming together from far and wide to do extraordinary things; real people, with delightful, authentic stories to tell, taking centre stage in a spectacular performance filled with wonder, warmth, wit and so much humanity.
"It will be all about how, through the recollections and stories and experiences we share, we can see how we are all connected - through time, to each other and to the Queen."
