Casualty is losing Duffy for good. Cathy Shipton, who has played Lisa ‘Duffy’ Duffin since the pilot in 1986, is exiting the BBC Studios produced series. She is one of the show's longest running cast members. While Duffy has come and gone in the Emergency Department throughout the years, this will be the character's final departure. Cathy's final appearance as Duffy will air in 2020. 
Newcomer Yasmin Kaur Barn has joined the cast of BBC One's daytime drama series Shakespeare & Hathaway – Private Investigators as a series regular for its just ordered third season. She will play PC Viola Deacon, a 20-something friend of Sebastian with boundless, puppy-like enthusiasm. Back in 2016, Yasmin Kaur Barn was cast as one of the leads in Fox's pilot Recon, which ultimately did no go to series. She has also appeared in an episode of BBC Three's Man Like Mobeen. 
After a five year break, Hugo Speer (The Musketeers) is returning to Father Brown. The actor, most recently seen on BBC One in U.S. acquisition London Kills, is set to reprise his role as Chief Inspector Valentine in the show's just announced eighth season. He last appeared in Father Brown's season two premiere back in 2014. Fan favourites Alex Price (Penny Dreadful) and Nancy Carroll (Prime Suspect 1973) are also returning for season eight and will be reprising their roles as Sid Carter and Lady Felicia, respectively. 
Babou Ceesay (Dark Mon£y, National Treasure) and Eve Myles (Keeping Faith, Broadchurch) have been tapped to star in We Hunt Together, Alibi's six episode cat and mouse thriller from Cheat scribe Gaby Hull and BBC Studios. 
BBC Studios and Anton have co-commissioned Cheaters, an eighteen episode short-form series from Misfits and The End of the F***ing World indie Clerkenwell Films. It is is eyed as a returnable series and each episode will run ten minutes. 
BBC Two drama MotherFatherSon will not be returning for a second season. News of this broke over the weekend, but sources are telling me that, contrary to other reports, the show was not axed due to poor ratings, but was instead designed to run a single season.
