Ten Doctors will take part in the BBC charity show The Big Night In later today on BBC One - a collaboration between the BBC's regular charity appeals Children in Need and Comic Relief. The event as a whole will run from 7pm until 10pm on BBC One.
The charity show will raise money for those on the front line dealing with the COVID-19 virus and pay tribute to all the unsung heroes trying to support their communities.
Hosted by Lenny Henry, who appeared in the last series of Doctor Who, the BBC One show will bring a night of comedy, music and live entertainment from the studio, linking up with a multitude of stars from their houses for an unmissable night.
The Doctors have recorded a message thanking front-line staff for their work during the coronavirus crisis. It will be broadcast just before the weekly Clap For Carers at 20:00 BST. Taking part are Tom Baker, Peter Davison, Colin Baker, Sylvester McCoy, Paul McGann, David Tennant, Matt Smith Peter Capaldi, Jodie Whittaker and Jo Martin.
Also appearing in the show is Matt Lucas, who joins former partner David Walliams in the first Little Britain sketch on TV for a decade, and Catherine Tate who bring reprises schoolgirl Lauren, currently struggling with being remotely educated by her teacher, played by David Tennant.
The three-hour show will aim to raise millions of pounds for vulnerable people around the UK who have been affected by the pandemic. The government has pledged to match all public donations, with a minimum of £20 million.
The programme also promises to "celebrate the acts of kindness, humour and the spirit of hope and resilience that is keeping the nation going".
