Further details of the Christmas special will be released nearer the broadcast, but the BBC confirms that the key cast of Arabella Weir (Beth), Alex Norton (Eric), Elaine C Smith (Christine), Doon Mackichan (Cathy), Jonathan Watson (Colin), Jamie Quinn (Ian) and Kieran Hodgson (Gordon) will appear in the special.
Graeme 'Grado' Stevely and Joy McAvoy, who play young couple Alan and Michelle, will not feature in the Christmas special but will be back for the fifth series, which is due to be filmed and shown next year.
The network says: "The Christmas special will be filmed in line with Covid-19 industry guidelines but will be taking a side-step from the current pandemic to focus on laughs."
Executive producer Steven Canny comments: "I'm delighted that Two Doors Down is going to give people the neighbourly get-together they have been missing out on in recent times. Eric, Beth, Colin, Cathy, Ian, Gordon and, of course, Christine get together to celebrate in the way that only they can. This special episode is the complete package of uncomfortable comments, barbed compliments and, of course, a ton of laughs."
