Sarah Hadland and Lolly Adefope are two of the names who have joined the cast of Hang Ups, the new C4 comedy starring Stephen Mangan as fallen-from-grace-therapist Richard Pitt.

Also appearing are Richard E. Grant (The Fear, Game of Thrones), Jessica Hynes (W1A), David Tennant (Broadchurch; Doctor Who), Katherine Parkinson (Humans; The IT Crowd), Karl Theobald (Alan Partridge, Green Wing), Arsher Ali (Ackley Bridge, Line of Duty), Celia Imrie (The Best Exotic Marigold Hotel) and Paul Ritter (Friday Night Dinner; No Offence).

Further guests are Charles Dance (Game of Thrones), Tolu Ogunmefun (Drifters), Monica Dolan (W1A), Sarah Hadland (Miranda, pictured), Conleth Hill (Game of Thrones), Lolly Adefope (Loaded), John Macmillan (Chewing Gum, Back) and Harry Lloyd (Manhattan).

Hang Ups is a farcical, dark and perceptive comedy about a man "trying to help other people keep their shit together while his own inexorably falls apart." Heavily improvised, each of Richard Pitt’s therapy sessions are startling, unpredictable, discomfiting and hilarious. 

It is due to air in 2018.
