TV tonight: a hilarious and heart-tugging finale for Big Boys | Television & radio

Big Boys

10pm, Channel 4

Jack Rooke’s semi-fictional comedy drama is a joyride of great gags, but at the heart of it have always been the heavier themes of mental health and grief. So prepare for the closing double-bill finale, as Danny (Jon Pointing) grapples with the end of university and thoughts of the future. Pointing, along with Dylan Llewellyn, who plays his best mate Jack, has been spectacular in telling this story – and it gets a fittingly poignant (but still hilarious) ending. Hollie Richardson

Planet Weird

7pm, Sky Nature

Planet Weird has set itself a UFC-worthy challenge this week: to show us the most gruesome and bizarre forms of wildlife combat. Fortunately, there’s no shortage of that in the animal kingdom. Standouts include neck-wrestling giraffes, a spider who dominates then devours their prey, and even the unassuming koala … who is not so cuddly, after all. Ellen E Jones

Call the Midwife

8.05pm, BBC One

Another week, another set of quietly subversive goings-on at Nonnatus House. Joyce (Renee Bailey) anxiously awaits her disciplinary hearing – when, in fact, she is the one who has been the victim of vile racist abuse. Meanwhile, a young couple who have struggled with addiction prepare for the arrival of their second child. Hannah J Davies

Unforgotten

9pm, ITV1

This hardy cold-case perennial has looked its age at various points during its sixth series but its climax over the next two nights should still be gripping. In this penultimate episode, arrests are made – but with lies abounding, hardly anyone seems to believe that’s the end of the matter. Meanwhile, Jess and Steve prepare for a showdown. Phil Harrison

Elgar’s Enigma Variations With the BBC Philharmonic

9pm, BBC Four

As with most of his pieces, Edward Elgar hid a riddle in Enigma Variations – and it is yet to be conclusively solved! The masterpiece is performed here by the BBC Philharmonic at Manchester’s Bridgewater Hall, in a programme that is completed by Arvo Pärt’s Swansong. HR

Miss Austen

9.05pm, BBC One

A weepy but uplifting end to the drama inspired by Jane Austen’s sister Cassandra, who in real life burned the author’s private letters. As Cassandra (Keeley Hawes) remembers Jane’s (Patsy Ferran) final years of ill health, in the present she sets out on a mission to find their niece a new home – and it involves some good old Austen-esque matchmaking.
