Giri/Haji continues to impress, Britannia and The Works Presents . . . and Live at the Apollo all return, and there's a special on Hollywood legend Gary Cooper . . .

Pick of the Day

Giri/Haji, 9.00pm, BBC Two

Still the best thing on of a Thursday night, this impressive Anglo-Japanese murder-mystery drama has been quite a journey so far as we reach the mid-point in the story.

Tonight's episode looks the business and is all about split-second moral decisions and their violent consequences, told in three chapters.

First up, the Mori brothers end up on opposite sides of a frantic Soho gun battle; in Tokyo, Toshio, Roy and Fukuhara confront the armed intruders sent to kill Fukuhara; then, Yuto relives the split-second decisions that brought them everyone to this point.

Britannia, 9.00pm, Sky Atlantic

The second season of the quirky drama from acclaimed writer Jez Butterworth and starring David Morrissey and Mackenzie Crook starts two years after General Aulus (Morrissey) claimed a foothold in Britannia.

The romanisation of this savage island is underway - but not without resistance. Meanwhile, an ancient figure has woken, and it could spell the end of everything, Celtic and Roman alike.
