Who Do You Think You Are? (BBC One, 9pm)

It's remarkable that it took this long for Olivia Colman to be featured in the genealogy strand.

Of course, when you are one of the most in-demand actresses of your generation, there's little wonder it's so tricky finding enough free time to trace your bloodline.

The star of Flowers, The Night Manager and countless other acclaimed projects discovers some surprises in her ancestral history, and a belief that most of those in her family tree emanate from Norfolk turns out to be far from the truth.

"I don't know what's happened in my family, and I don't know who's been forgotten... and it might be quite nice to remember them again," she explains.

Olivia is amazed to discover that she needs to travel to India to find out more about her great-great-great grandmother Harriot, who was an orphan in 1811 on a ship bound for England from Calcutta.

Harriot's father was an an Englishman, but the identity of her mother, who gave birth to her in a remote Indian village, is a mystery Olivia delights in solving.

The Norwich-born thespian's own history is more well-documented than any of her family's.

She caught the acting bug in a school version of The Prime of Miss Jean Brodie. While studying teaching in Cambridge, she honed her acting skills at Bristol Old Vic Theatre School.

By 1999, Olivia graduated, and while at Cambridge University Footlights Dramatic Club, she met fellow rising stars David Mitchell and Robert Webb.

It marked the beginning of many collaborations. Radio show That Mitchell and Webb Sound naturally paved the way for TV hit That Mitchell and Webb Look, while appearances in their hit sitcom Peep Show also kept the wolf from the door.

She came to many peoples' attention in surreal medical comedy Green Wing. Roles in TV hits Beautiful People and Skins didn't hurt either, while her rib-tickling turn as a licentious copper in Hot Fuzz ensured she'd become an ITV2 staple for years.

However, it was as crime buster Ellie Miller that her status as national treasure was affirmed. Three series of Broadchurch left millions perched on the edge of their seat.

Naturally Olivia has plenty of irons in many fires at the moment. She's playing Madame Thenardier in a TV version of Les Miserables; will portray Queen Anne in The Favourite (in which she re-teams with Yorgos Lanthimos, director of The Lobster), and will take over as Queen Elizabeth II in TV smash The Crown.

The latter has already won a Golden Globe for Claire Foy in the same role, and there's a good bet Ms Colman will also be in the running in a year or so.

If so she can add it to the one she won for The Night Manager; the Baftas she won for Twenty Twelve, and Accused, and the assorted other gongs weighing down her shelves.

"I'm interested in the people that have gone before," she explains in WDYTYA. "There's a fragility to life, and also when you go, will you be forgotten?

Considering her impressive body of work, there's little chance of anyone forgetting Olivia Colman.

Puppy Love (BBC1)

Some mutts would much rather roll around in something smelly or run through a muddy puddle than subject themselves to a bath. But there are dogs who have a taste for the finer things in life and enjoy being well turned out - which is where Mucky Pups, Wales' first doggy boutique and spa, comes in. The biggest business of its kind in the UK, it offers 'pawdicures', blueberry and vanilla 'furcials' and for the discerning pooch, the full-day 'Dogfather' treatment, complete with a massage and canine cologne. This documentary discovers how its owner Leanne has become one of Wales most successful young female entrepreneurs, and meets some of the staff and customers. It also learns more about Leanne's newest business idea, which sees her venturing into the more controversial world of breeding.

The Jumbo Jet: 50 Years in the Sky (C5, 9pm)

This year has been a big one for landmark anniversaries - 100 years since women got the vote, 70 years of the NHS - and there is another milestone which has also had a staggering impact on our daily lives. Fifty years ago this summer, the very first jumbo jets, the Boeing 747s, began their service. Ushering in the 'jet-set age', they revolutionised travel and made the world feel like a closer place. In this two-part documentary, we hear from some of Boeing's 'incredibles' - the name given to the engineers and test pilots whose tireless work made the 747 prototype a reality - as they recall the dramatic stories of the plane's early flights. It seems that conquering the skies was turbulent at times.

Versailles (BBC2, 9.30pm)

A funeral brings key players to the palace, with Cardinal Leto from the Vatican eager to exercise closer control over Louis' ambitions, and Louis seeking to cultivate Leto's favour. Emperor Leopold still intends his niece Eleanor to marry the King of Spain, while Delphine speaks out against the latest crackdown on Protestants at Versailles, increasing the Chevalier's admiration for her, and Philippe, aided by Marchal's researches, discovers a secret that rocks the foundation of Louis' right to rule.
