Simon Amstell (Popworld, Never Mind the Buzzocks) is Simon, a mildly self-obsessed, claustrophobic narcissist, trying desperately to heal his broken family so he can feel something real in his life. BAFTA award-winning Rebecca Front (The Thick of It, Nighty Night, The Day Today) is his mother, Tanya. She is marrying a man with a big house. James Smith (In the Loop) is Clive. He is a man, with a big house. Linda Basset (The Reader, East is East, Larkrise to Candleford, The Hours) is Grandma, desperate for everyone to be happy or at least agree that they are happy and not cause any bother. Geoffrey Hutchings (Benidorm, Sunshine) is Grandpa who, aside from his prostate cancer, is no bother. Samantha Spiro (Cor Blimey, Tomorrow La Scala) is Liz, who isn't so keen on Simon because he's Tanya's son and Jamal Hadjkura is her son Adam, who has gone a bit odd.
