Like that other fine espionage drama The Americans, the secret of the Deutschland series has always been its canny mixing of personal and political priorities. Here, Martin (Jonas Nay) is approached by a veritable alphabet soup of international intelligence agencies – the HVA, the CIA, the KGB and the BND among them – but, as ever, he is really motivated by the need to protect his son, who increasingly feels like a bargaining chip. Oh, and he’s been asked to infiltrate a terrorist group, too. It’s all go. Phil Harrison
8pm, BBC Two
Plugging the gap before a new series of Gardeners’ World starts next week, a special hour-long amuse-bouche in which Monty Don and his green-fingered chums take a look back at highlights from previous shows. Here be alliums and auriculas, creative containers and houseplants. Ali Catterall

Gregg Wallace’s Big Weekend in Venice
9pm, Channel 5
The presenter hits Italy’s dampest tourist attraction. Venice isn’t cheap, but Wallace will be offering tips for enjoying the city on a budget. He will also tuck into the culture, the history and, inevitably, the food. A nice appetiser for the city breaks we once again may soon be able to enjoy. PH
Later – With Jools Holland

Another strong Friday lineup. Tonight, Laura Mvula digs into the Later archive and discusses her third album; Paul Weller invites us into his studio, and there is a TV debut for the excellent London four-piece Dry Cleaning, who perform live at the Moth Club ahead of their album, New Long Leg. PH
The Graham Norton Show
10.45pm, BBC One
More socially distant socialising, as Norton welcomes the director Amy Poehler to discuss her feminist teen flick Moxie, the actor turned podcaster Minnie Driver, and the actor Jennifer Garner, who’s talking up her new Netflix comedy Yes Day. Music is from Tom Odell, returning with a darker sound. Hannah J Davies
Blithe Spirit (David Lean, 1945), 3pm, Talking Pictures TV
This spirited British take on US fantasy screwball comedies retains all the wit and style of Noël Coward’s play. Rex Harrison plays a widowed novelist on his second marriage (to Constance Cummings) who is haunted by his first wife (Kay Hammond). Margaret Rutherford steals every scene as a dotty medium. Paul Howlett
