Big Boys
Sunday, 10pm, Channel 4
Prepare for belly laughs and lots of sobbing: it’s the third and final chapter of Jack Rooke’s touching semi-autobiographical comedy about the friendship between a young gay man and his straight best mate. As the final year of university looms, Jack (Dylan Llewellyn), Danny (Jon Pointing) and the gang are forced to make big decisions about their futures – including Jack’s dissertation title (“To Bum Or Not to Bum” is one idea). Before things get serious, though, the opening double bill kicks off with a Faliraki holiday – complete with all the naughty gags, fun 2010s references (look out for the Rylan cameo) and lovely heart-to-hearts that make this show such a hit. It will be missed. Hollie Richardson
Unforgotten
9pm, ITV1
Newly acquainted detective duo DCI Jessica James (Sinéad Keenan) and DI Sunny Khan (Sanjeev Bhaskar) may have got off to a bumpy start last season, but they’re back with a grisly new case to solve (which is, at least, a welcome relief from their personal dramas). When a spine is found on the Whitney Marsh, there are four potential suspects for Jessica and Sunny to investigate. Continues on Monday. HR
Who Wants to Be a Millionaire? Celebrity Special
8pm, ITV1
Another pair of celebrities sit in the famous studio, trying to answer 15 questions to win £1m for charity. You can’t fault the lineup for variety: will actor Julie Hesmondhalgh or former world cruiserweight boxing champion Tony Bellew display better general knowledge under pressure? Jack Seale
Call the Midwife
8.05pm, BBC One
What a load of rubbish: a bin strike means piles of garbage piling up in Poplar, causing the nuns to dodge rats on the way to work. As Weil’s disease leads to illness, death and bad-tempered council meetings, an obstreperous patient brings grief for Nurse Joyce (Renee Bailey). JS
Boyzone: No Matter What
9pm, Sky Documentaries
In the second episode of this sobering three-parter, the cracks are starting to show for the boyband, who – says former member Shane Lynch – were tired and broken by the end of the 90s. The grim spectre of the tabloids also looms, as they vie to out Stephen Gately as a gay man. Hannah J Davies
Miss Austen
9.05pm, BBC One
Keeley Hawes plays Jane Austen’s sister, Cassandra, in this fantastic reimagining of the juicy story behind her decision to burn the novelist’s private letters. She continues to read them in secret, away from scheming cousin Mary (Jessica Hynes), and is reminded of a great young romance through her sister’s words. HR
Film choice
Scott of the Antarctic, 1.15pm, BBC Two
We do love a heroic failure in this country, and there’s none more so than explorer Robert Scott, who set out to be the first to reach the South Pole but was beaten to it by a smarter man in the Norwegian Roald Amundsen. There’s a lot of stiff upper lips and frostbitten toes in Charles Frend’s fact-based rendering of the tragic tale, with the great John Mills the epitome of gentility and pluck as his expedition tromp heavily through beautiful Technicolor snowscapes and -40C temperatures towards second place. Simon Wardell
Quatermass and the Pit, 11.50pm, Sky Arts
Hammer’s 1967 adaptation of the third of Nigel Kneale’s celebrated BBC sci-fi dramas is easily their best, gripping and well-acted with pretty decent special effects. Andrew Keir is a thoughtful but twinkly-eyed Quatermass, a rocket scientist intrigued when work on a Central line extension in London digs up weird prehistoric ape skulls next to an unusual, possibly alien craft. Supported by palaeontologists James Donald and Barbara Shelley and butting heads with Julian Glover’s blinkered military type, he uncovers an ancient, malevolent secret. SW
