The novel was dramatised as the 1969 film Decline and Fall... of a Birdwatcher, starring Robin Phillips, and also by Jeremy Front in a 2008 BBC Radio 4 production starring Alistair McGowan as Pennyfeather, Jim Broadbent as Grimes, Andrew Sachs as Prendergast, Edward Hardwicke as Dr. Fagan, Jonathan Kidd as Philbrick, Joanna David as Margot Beste-Chetwynde, Emma Fielding as Flossie, and Richard Pearce as Peter.
In 2017 the BBC produced a three-part TV dramatisation[13] starring Jack Whitehall as Paul Pennyfeather, David Suchet as Dr Fagan, Eva Longoria as Margot Beste-Chetwynde, Douglas Hodge as Captain Grimes, and Vincent Franklin as Mr Prendergast.[14] The production was the book's first television adaptation, and received largely positive reviews. Alastair Mckay with the Evening Standard called it "delicately constructed and pitch-perfect."[15] Ellen E. Jones remarked on the show's "many enjoyable performances," especially that of Hodge as the "drink-soaked deviant" Captain Grimes, adding, "Give him a spin-off series immediately."[16]
