Read on for everything you need to know about the Ghosts cast, ahead of the Christmas 2023 special on BBC One.

Ghosts cast: Who stars in the 2023 Christmas special?

Charlotte Ritchie plays Alison

Who is Alison? Alison is a cash-strapped woman who finds out that she has inherited a country manor from her "step-great-auntie" – a distant relative who died leaving no direct descendants.

In the first series, she has a near-death experience that gives her the ability to see ghosts, allowing her to get to know the larger-than-life personalities haunting her new home. Over time, they become unlikely friends, but life in Button House still has plenty of challenges – especially when Alison becomes pregnant.

Where have I seen Charlotte Ritchie before? She played Nurse Barbara Gilbert on Call The Midwife until making a heartbreaking exit in season 7, and previously starred in Channel 4 comedy Fresh Meat as Oregon.

Since leaving Midwife, she has also co-starred in Netflix's Feel Good and E4's Dead Pixels, as well as making guest appearances in Doctor Who and Death in Paradise. More recently, she joined the Grantchester cast for season 7, playing a love interest to vicar William Davenport (Tom Brittney), and took on a dark new role for You season 4.

Kiell Smith-Bynoe plays Mike

Who is Mike? Mike is Charlotte's husband, who moves with her to Button House to help renovate the dilapidated property. He isn't able to see the ghosts like Alison can, but does believe that they exist and supports her in coping with them where he can.

The writers of Ghosts have dismissed the idea of finding a way for Mike to see the paranormal tenants himself, feeling it would change the premise of the show too radically and irreversibly. Besides, Mike gets into plenty of hijinks all on his own, with the season 4 finale following his ill-fated purchase of a taxidermy bear.

Where have I seen Kiell Smith-Bynoe before? Smith-Bynoe is best known for playing Dean in acclaimed Channel 4 comedy Stath Lets Flats, while he has also appeared in Man Like Mobeen, Death in Paradise and Bloods.

He made a guest appearance in Daisy May Cooper comedy The Witchfinder and featured in Dave mockumentary Live at the Moth Club. Most recently, he starred alongside Lily Allen and Freema Agyeman in Sky comedy Dreamland, before being named the new host of The Great British Sewing Bee.

Mathew Baynton plays Thomas

Who is Thomas? A failed romantic poet who now haunts Button House. He quickly becomes infatuated with Alison, and finds it hard to accept that she isn't interested in him.

Where have I seen Mathew Baynton before? The Horrible Histories and Yonderland star first came to national attention in the Gavin & Stacey cast, where he played Smithy's dim-witted friend and colleague, Deano. He teamed up with James Corden once again on comedy-drama series The Wrong Mans.

His other television credits include ITV's Vanity Fair, The Split, Peep Show and Sky's You, Me and the Apocalypse. This Christmas, you can also find Baynton in family blockbuster Wonka, which is co-written by Simon Farnaby (more on him below).

Simon Farnaby plays Julian

Who is Julian? A Conservative MP who passed away under embarrassing circumstances. Hint: he's not wearing any trousers. Julian also has the ability to move objects in the real world, but only short distances and with great concentration. His fellow ghosts regard Julian as morally bankrupt, although he has shown a softer side from time to time.

Where have I seen Simon Farnaby before? As well as Horrible Histories and Yonderland, Simon Farnaby has also had roles in Detectorists and This Time with Alan Partridge, as well as a brief cameo appearance in Rogue One: A Star Wars Story.

Behind the camera, he is known for co-writing family adventure Paddington 2, which received critical acclaim and was a box office hit, and reunited with director Paul King for Hollywood blockbuster Wonka, starring Timothée Chalamet.

Lolly Adefope plays Kitty

Who is Kitty? One of the ghosts haunting Alison and Mike, Kitty is a Georgian noblewoman who is very kind and easily excited. Sadly, she's also rather naive and this has been exploited in the past – including by her mean sister.

Where have I seen Lolly Adefope before? The comedy star played infuriating roving reporter Ruth Duggan in This Time with Alan Partridge, while she also stars in US comedies Shrill and Miracle Workers.

She also competed on the fourth season of Greg Davies and Alex Horne's smash hit Taskmaster. This year, we've seen her in offbeat Channel 4 sitcom Everyone Else Burns and Emerald Fennell's awards contender Saltburn.

Martha Howe-Douglas plays Lady Button

Who is Lady Button? A distant relative of Alison who passed away in Button House during the Edwardian era. She starts out extremely pompous and elitist, still considering the house to be her home above all else. However, over time, she has warmed to her fellow ghosts as well as the latest living owners.

Where have I seen Martha Howe-Douglas before? The Horrible Histories and Yonderland regular also featured in Doctor Foster and made a surprise appearance on EastEnders back in 2018. More recently, she has guest starred in BBC One sitcom Motherland and Sky comedy Breeders. In 2023, she revealed to RadioTimes.com that she almost played Alison in Ghosts.

Ben Willbond plays The Captain

Who is The Captain? A former army officer who fancies himself the leader amongst the spirits in the mansion. It has been strongly implied that the Captain is gay, with one emotional episode revealing he developed feelings for one of his fellow soldiers during World War II. However, he did not come out of the closet before his death – and may not completely understand his feelings to this day.

Where have I seen Ben Willbond before? Another Horrible Histories and Yonderland favourite, Willbond has also featured in comedies such as The Thick of It, Tracey Ullman's Show, There She Goes and Alma's Not Normal. He also appeared in Neil Gaiman's fantasy series Good Omens. On the big screen, you may recognise him from belated sequel Bridget Jones's Baby. He collaborated with Ghosts co-star Laurence Rickard on the UKTV sci-fi feature We Are Not Alone.

Jim Howick plays Pat

He currently stars in another BBC sitcom, Here We Go, while he also took a dramatic turn for ITV thriller Hollington Drive.

Who is Robin? A caveman and the longest serving ghost in the house by far, Robin also has the ability to make the lights in the house flicker.

Where have I seen Larry Rickard before? As well as Horrible Histories and Yonderland, Rickard has also written for and starred in Tracey Ullman's Show and Tracey Breaks the News. He co-wrote and appeared in UKTV sci-fi comedy We Are Not Alone, alongside Ben Willbond.

Laurence Rickard plays Sir Humphrey Bone

Who is Sir Humphrey Bone? Humphrey is a ghost from the Tudor period who was beheaded. As a result, his head often detaches from his body and goes missing around the house. In season 3, we learn more about the surprising circumstances that led to his grisly fate.

Where have I seen Larry Rickard before? See above.

Sutara Gayle plays Mike's mum, Betty

Who is Betty? Betty is Mike's loving mother who stayed at Button House for Christmas 2020. Much like her husband, she finds it difficult to sit down and relax, preferring to find things to help out with.
