Steve Pemberton and Reece Shearsmith have started shooting on the fourth anthology of Inside No.9 comedy dramas.

After the success and critical acclaim of the first three series the show will return to BBC Two with another stellar line up. Each of the six films will again feature new characters, new venues and a new twist on the number nine. Filming continues at locations in West London, Pinewood Studios and Waltham Abbey until Easter.

The guest cast for the new series includes Zoë Wanamaker (Harry Potter); Noel Clarke (Kidulthood); Emilia Fox (Silent Witness); Monica Dolan (W1A); Sian Gibson (Car Share); Nick Moran (Lock, Stock And Two Smoking Barrels); Nigel Planer (Episodes); Kenneth Cranham (Maleficent); Fenella Woolgar (War And Peace); Phoebe Sparrow (Downton Abbey); Rory Kinnear (Count Arthur Strong); Marcia Warren (Sherlock); Bill Paterson (Fleabag); Helen Monks (Raised By Wolves); Tanya Franks (Chewing Gum); Kevin Eldon (Damned); Hattie Morahan (Outnumbered), Nicola Walker (Unforgotten); Miranda Hennessy (Pramface); Weruche Opia (Bad Education) and David Calder (The Moonstone).

Commenting on the new series, Reece Shearsmith and Steve Pemberton said: “We feel ridiculously privileged to find ourselves at Pinewood Studios filming a new set of episodes (though sadly not in Studio 9). We are getting through more actors than Midsomer Murders and it's a dream to work with the country's finest once again. As ever we've attempted a real mix of styles and genres, including one really brilliant episode and one really disappointing one; we look forward to viewers debating which is which."

Shane Allen, Controller, Comedy Commissioning, says: “Reece and Steve continue to dazzle and amaze with their ever inventive powers of story-telling. Their terrific writing has lured the cream of British acting talent to serve up six completely new and sublimely conceived treats. They transcend the parameters of genre limitations with this widely admired series”.

Adam Tandy, Producer, says: "This year's films once again take place at, in, on or around a big number 9, all of them entirely different and each one filled with a unique and delicious mixture of comedy, drama, love, intrigue, ancient curses, industry gossip, room service, and murderous intent. Take your pick."

Inside No. 9 was commissioned by Shane Allen, Controller, BBC Comedy Commissioning. It will be executive produced by Jon Plowman with Adam Tandy as producer. Jim O'Hanlon joins the directing team for the first time, alongside Graeme Harper and David Kerr. It is a BBC Studios production.
