TV Times tops picks for tonight

What’s on telly tonight? Here the TV Times team of expert reviewers highlight three of the best shows on telly tonight for Sunday 5th November

Blue Planet 2, 8.00pm, BBC1

In an episode that seems more like a journey into outer space than a voyage into our global waters, Sir David Attenborough introduces us to the remarkable and often downright bizarre sea life that dwells in the deepest areas of our oceans, where the lack of sunlight and high pressure results in only the toughest – and oddest – surviving. High on the weirdness scale is the sea toad (a fish with legs!) and a barreleye fish that has a transparent head so it can see everything above it. But prepare to be terrified by the creepy fangtooth, with its huge teeth and pressure sensors on its body that sense when any prey is nearby. There’s also remarkable footage of volcanic hot-spots, where life still thrives. Rating: *****

Sheridan, 9.00pm, ITV

A one-off special featuring TV's favourite entertainer

Belting out Cilla Black’s classic hits, starring in hard-hitting dramas such as The Moorside, or playing for laughs in sitcoms like Gavin & Stacey, it seems there’s little Sheridan Smith can’t do. Now, the actress is taking over ITV with a one-off musical special. Chatting to host Alexander Armstrong, she looks back at memorable roles in TV dramas Cilla and Mrs Biggs, and opens up about losing her father to cancer last year. Sheridan also performs tracks from her debut album (out 3 November), including Don’t Rain on My Parade from hit musical Funny Girl, accompanied by a live orchestra. This is Sheridan as you’ve never seen her before. Rating: *****

The Last Post, 9.00pm, BBC1

Captain Joe Martin started off as one of our least favourite characters but, thanks to Jeremy Neumark Jones’s impressive performance, his softer side has emerged

Captain Joe Martin started off as one of our least favourite characters but, thanks to Jeremy Neumark Jones’s impressive performance, his softer side has emerged and, after saving little George, he’s now firmly in our good books! In this tense finale, Joe is on trial for disobeying orders, but as Ed, Honor and Martha try to get justice for him, it becomes clear there’s more to the case than meets the eye… Rating: *****
