Everything you need to know about Strictly Come Dancing 2021
When does Strictly start?
As usual, Strictly Come Dancing is set to start the series with a launch show that will introduce the celebrity contestants and match them with their partners.
The 2021 launch show is set to begin on Saturday, 18 September at 7.45pm on BBC One and the bumper episode will continue until 9.30pm.
Last year, filming restrictions meant that the couples being matched had been pre-recorded rather than the whole group waiting to see who their partner was like in previous years.

That also meant that the show didn't need to take its traditional two-week break before live shows for the couples to rehearse as they'd already met each other.
Strictly will follow the same format change this year, meaning we can get stuck straight into the live shows from Saturday, 25 September, explaining the later start date than previous full-length series years.
Who is on Strictly this year?
Over the summer Strictly fever really set in as this year's celebrity line-up was announced.
The 15 celebrities putting their best foot forward this year are:

Watch: Who is Strictly's Rose Ayling-Ellis?
This year will feature Strictly's first-ever all-male couple as former Bake Off winner Whaite gets a male pro partner, while EastEnders actor Ayling-Ellis is the first deaf contestant to take part.
Who are the pro dancers on Strictly 2021?
On the pro dancer side, we'll see four new performers join the show - Cameron Lombard, Kai Widdrington, Nikita Kuzmin and Jowita Przystal.
Returning for another series are some familiar names, including female pros Amy Dowden, Dianne Buswell, Karen Hauer, Katya Jones, Luba Mushtuk, Nadiya Bychkova, Nancy Xu, and of course twice-in-a-row series champion Oti Mabuse.
The male pros coming back for 2021 are Aljaž Škorjanec, Giovanni Pernice, Gorka Marquez, Graziano Di Prima, Johannes Radebe, and Neil Jones.
Janette Manrara may not be on the pro dancer roster this year, but she'll still be an integral part of the show as the new host of spin-off Strictly: It Takes Two.
Meanwhile, hosts Claudia Winkleman and Tess Daly are teaming up again for the main shows.
Who is on the judging panel?
Strictly doesn't like to shake up its judging panel as much as many other reality shows, but this year there'll be a new addition thanks to ongoing problems caused by the pandemic.
Like last year, regular judge Bruno Tonioli will be stuck in the US for his Dancing With The Stars commitments and because of travel restrictions will not be able to fly back and forth to the UK.
This series, the judging panel is back up to the full four, with pro dancer Anton Du Beke finally getting his seat at the desk.
Du Beke is the only dancer to have competed in every series since the show launched in 2004, so it's a big change to see him judge for a full series (he was a guest judge covering for Most Mabuse for two weeks last year).
Anton said of his new role: “My loves I cannot tell you how thrilled I am to be stepping into Bruno’s brogues for the next series of Strictly. It’s a dream come true to be judging alongside the best of the best and I promise to be kinder to all the couples than any of them have ever been to me.”
He'll be joining head judge Shirley Ballas and regular fixtures Motsi Mabuse and Craig Revel Horwood who are all returning.
Will Strictly be back to normal this year?
Yes and no...
Strictly fans will be glad to know that the number of couples is back up to the full 15 this year after a smaller number of contestants and shorter competition in 2020.
Excitingly, a studio audience will also be allowed in for filming this year which will be welcomed by the couples as they'll have plenty of people to cheer them on compared to last year's empty ballroom.
Themed weeks are also back on the menu, so look out for old favourites like Halloween, musicals and movies weeks.
However, there is one big hole in the Strictly format we've come to know and love, as unfortunately the series will not be heading to Blackpool for the second year in a row.
The annual trip to Blackpool's Tower Ballroom has become a huge goal for the couples as it marks the midway point in the series and gives them the chance to dance in one of the ballroom world's most famous venues.
But producers just could not make the trip work in line with COVID filming guidelines this year – we're keeping our fingers crossed for a triumphant return in 2022.
