The cast list for the fifth 2024 Doctor Who series episode Dot and Bubble, was released on the BBC One listing for the programme.

The world of Finetime, a colony on an alien planet, seems happy and harmonious — but an awful terror is preying on the citizens. Lindy Pepper Bean (Callie Cooke) must contend with an out-of-control dangerous situation. A gurgling, slobbering, munching sound can be heard from around the corner and her friends are mysteriously disappearing. Can the Doctor and Ruby make the denizens of Finetime see the truth before it’s too late?
