The 80s legal drama is reborn with a new lead as Matty plots to convince hirers they need an older woman for the job. Plus: The Great British Bake-Off cooks up this year’s final. Here’s what to watch this evening

9pm, Sky Witness
A sparky new legal comedy drama starring Oscar-winner Kathy Bates, who is great as whip-smart, empathetic lawyer Madeline “Matty” Matlock in this spin-off from the 80s classic. Matty left law 30 years ago, but now in her 70s, wants to practise again. When she believes she is passed over for a role because of her age, Matty uses her wits to sneak into the firm, telling the hirers why being an older woman is useful: “Nobody sees us coming.” But can she convince junior partner Olympia (Skye P Marshall)? Hollie Richardson
