I read that after current filming wraps there's a much larger block entering production in the fall. Possibly just further specials if there's more than one, or possibly season 14?
Gotta admit I have missed Russell's work ethic. It gives me serious anxiety when I think of the fact that seasons of the show under Chibnall would finish airing before scripting for the next had even begun, and from a fan point of view, the complete radio silence for whole years at a time was so frustrating.
But knowing Russell has probably started writing on season 14 and that they've hit the ground running with production so quickly after everything was signed? A literal king, the Madonna of screenwriting.
