Best TV shows on TV tonight
His Dark Materials, 7pm, BBC One
This sensational adaptation of Philip Pullman’s trilogy has always managed to blend stunning fantasy with high emotion, but the bar has been raised even higher in the final run, which begins with gung-ho Lord Asriel (James McAvoy) planning to wage war against the menacing Authority.
Fearless teenager Will (Amir Wilson) is due to join the battle, but first he wants to locate pal Lyra (Dafne Keen), whose wily mum Mrs Coulter (Ruth Wilson) has kidnapped her... With heartfelt performances from the two young leads once more, some jaw-dropping new worlds to explore and danger looming, it looks set to be a breathtaking swansong.

Snow Dogs, 9 pm, BBC Two
Snowy landscapes, Alaskan huskies and a treacherous week-long camp out in the frozen wilderness of Canada’s Yukon make for a dramatic but heart-warming Christmas tale. Wildlife film-maker Gordon Buchanan takes on his greatest challenge yet when he attempts to master a team of seven huskies and lead them for eight days across Canada’s unforgiving north. The art of ‘mushing’ is harder than it looks, especially when he has to negotiate sled crashes, blizzards and even losing two of the huskies miles from civilisation. But the bond he develops with the dogs is truly touching… ★★★★ HD
Best box set on TV tonight
The Flatshare, Paramount Plus
Tiffany and Leon are flatmates, but there's nothing conventional about their living arrangements. Despite sharing the same place, they've never actually met with Tiffany having the flat from 8 pm - 8 am, and Leon having it from 8 am - 8 pm. Over time the pair learn more about each other through post-it notes and start to develop an attraction to one another, even though they've never had an in-person conversation.
Jessica Brown Findlay and Anthony Welsh are excellent in the leading roles and with all six episodes now available on Paramount Plus, it's the perfect show for binge-watching. But will Tiffany and Leon actually become an item? You'll have to watch and find out!

Best film on TV tonight
Saving Mr Banks, 4:10 pm, BBC Two
Walt Disney becomes determined to adapt Mary Poppins into a film, but faces an obstacle in the shape of author PL Travers, who resists the idea of a sentimental Hollywood version of her book. As the movie mogul's charm offensive comes unstuck, he begins to realise why the story is so important to its creator. Fact-based drama, with Emma Thompson, Tom Hanks, Paul Giamatti and Colin Farrell.
