Saturday's best TV: Strictly Come Dancing - The Final; Feud: Betty and Joan

Talking Pictures: Roger Moore
5.05pm, BBC Two

Just as Tom Baker will always be the quintessential Doctor for many, so the late Roger Moore, he of the quizzical eyebrow and perfect diction, will for ever be the ultimate 007 for a generation of cinemagoers. In this homage, his Saint co-star Sylvia Syms trawls through Auntie’s archives for interviews with this charming, funny and self-deprecating chap, a tireless ambassador for Unicef, who right from the off seemed born to play Bond. Ali Catterall

Word of the Year 2017
6pm, Channel 4

Exploring the host of new words to make it into the lexicon this year, Jo Brand, Sara Pascoe, Nish Kumar, Aisling Bea, Rik Edwards and Jamie Laing assemble to determine the subtle difference between a snowflake and a broflake, find out what the merry hell lagom is (it’s like hygge) and whether they’ve ever been duped by a hatfish, a person who looks starkly different with a hat than without when viewed on, say, Tinder. God help us all. Ben Arnold

Strictly Come Dancing: The Final
6.30pm, BBC One

All the stops are pulled out for the festive extravaganza: there’s Ed Sheeran crooning; all the dancers returning for a group performance; and the chance for viewers to vote for their favourite couple. The new queen of the panel, Shirley Ballas, will be putting her foot down for one last time this series as the couples dance for the trophy. It’s been a season of shocking eliminations, but if Debbie McGee doesn’t win there’ll be outrage. Hannah Verdier

Feud: Bette and Joan
9pm, BBC Two

The televisual equivalent of a hot crumpet on a cold winter afternoon, this deliciously indulgent eight-parter dramatises the relationship between Bette Davis and Joan Crawford with an all-star cast (Susan Sarandon and Jessica Lange lead). In this series opener, we discover the thorny origins of Whatever Happened to Baby Jane?. As Catherine Zeta-Jones’s Olivia de Havilland sighs: “They hated each other, and we loved them for it.” Sophie Harris

Witnesses: A Frozen Death
9pm, BBC Four

The concluding double bill of the French thriller begins with Sandra waking up drugged and captive. Meanwhile, her fellow cops make painfully slow progress, although Catherine, still determined to locate her baby, brings energy and smarts to her freelance investigation. Despite some schlocky moments, it has been an eerie, beautifully shot series that’s drawn powerful performances from its female leads, Audrey Fleurot and Marie Dompnier. Jonathan Wright

Titanic: 20 Years Later with James Cameron
9pm, National Geographic

James Cameron’s film utilised extensive research to ensure the accuracy of every facet of the doomed liner, yet many guesses still had to be made. Two decades on, Cameron’s continued fascination with the disaster has led to the recruitment of experts to re-evaluate that research using new evidence. Including inherited recollections from ancestors of the passengers, this is a worthy companion piece. Mark Gibbings-Jones

CMA Country Christmas 2017
8pm, Sky Arts

There have been many great country Christmas songs: one thinks, naturally, of Faron Young’s I’m Gonna Tell Santa Claus on You and Hank Snow’s version of Rudolph the Red-Nosed Reindeer. It is regrettably unlikely that anything of quite that quality will be yielded by this iteration of this glitzy schmaltzfest. Reba McEntire hosts performances by Nashville’s reigning aristocracy, including Alan Jackson, Luke Bryan and Lady Antebellum. Andrew Mueller

Film choice

Chocolat (Lasse Hallström, 2000) 12.45am, Sky Arts
In 1950s Gascony, the village of Lansquenet is a museum piece, preserved in all its staunch Catholic virtues by its stern mayor (Alfred Molina). Then, in breezes Juliette Binoche’s Mme Rocher to turn the old bakery into a chocolate shop – and at Lent, too. There is a reactionary backlash, but her sweet wiles win over many of the villagers, not to mention handsome Gypsy Johnny Depp. Hallström’s adaptation of Joanne Harris’s novel grows sickly, but it’s hard to resist.

Possessed (Curtis Bernhardt, 1947) 3.20pm, BBC Two
Joan Crawford is on form as a woman pushed to nervous breakdown. In true noir style, it opens with Crawford’s Louise wandering the streets of downtown LA at dawn. Taken into hospital and sedated, she starts to relive, in melodramatic flashbacks, the emotional hammer-blows that have reduced her to this. She’s a psychiatric nurse guilt-ridden when a patient drowns herself, suspecting Louise of having an affair with her husband (Raymond Massey). Reality and neurosis converge in Bernhardt’s dreamlike drama. PH

Return of the Musketeers (Richard Lester, 1989) 4.50pm, Film4
A last hurrah for the gang first assembled by Lester in 1973. Michael York, Oliver Reed, Frank Finlay and Richard Chamberlain are still all-for-one in an adventure set 20 years on. It may not have the energy you’d expect from a George MacDonald Fraser treatment, but there’s plenty of action as the French heroes try to save England’s Charles II from the chop. PH

Shadow of the Vampire (E Elias Merhige, 2000) 12.45am, BBC Two
This enjoyable fictional account of the making of the 1922 vampire classic Nosferatu gets weird and silly. According to Merhige’s scheme of things, obsessive German director FW Murnau hired a real vampire to play his bloodsucking villain, Count Orlok. It doesn’t quite sustain the macabre conceit and some of the humour is unintentional, but the droll teaming of John Malkovich as Murnau and Willem Dafoe as the actor Max Schreck is highly entertaining.
