Staying in tonight? Here's what to watch on the box
The Charlie Hebdo attacks, Frank Gardener on Who Do You Think You Are and the most frightening horror movie ever made are among tonight's picks
WHO DO YOU THINK YOU ARE?
The longer this series goes on, the less immediately recognisable the celebrity ancestor hunters become. The stories remain largely fascinating, though. Tonight, BBC news correspondent Frank Gardner sets out to find out whether there is any truth in his late mother’s claim that her side of the family arrived in Britain with the Normans. Along the way, he traces his ancestry back to his 10-time great-grandfather Sir Michael Stanhope, a knight of the Tudor court, who was accused of treason. But the journey does not end there, as he gets much closer to his mother’s suspicions than he could ever have imagined.
CHARLIE HEBDO: THREE DAYS THAT SHOOK PARIS
EYEWITNESSES and survivors recall January’s attacks in France by Islamist militants against satirical magazine Charlie Hebdo, the police and a Jewish supermarket, terrorist strikes that left 20 people dead and sent shockwaves through much of the world.
MOVIE: THE EXORCIST
Sky Movies, 11.40pm
(1973, Horror) William Friedkin’s film is still the scariest and most unsettling horror movie ever made. Not so much because of Linda Blair’s head-spinning, pea-soup-vomiting, backwards-talking antics (though they’re properly spooky), but because of the air of everyday realism that dominates everything else.
Terrific turns from Ellen Burstyn, Jason Miller and Max von Sydow, and brilliantly smoky, atmospheric cinematography from Owen Roizman.
THE SECRET RULES OF MODERN LIVING: ALGORITHMS
Without people noticing, modern life has been taken over. Algorithms run everything, from search engines on the internet, to satnavs and credit card security. They even help people travel the world, find love and save lives. Here, mathematician Marcus du Sautoy demystifies this hidden world by showing some of the most essential algorithms. He reveals where these 2,000-year-old problem-solvers came from, showing how they work, what they have achieved and how they are now so advanced they can even program themselves.
THE WORKS PRESENTS
New series of the arts show with John Kelly. He travels to London to talk to Irish playwright Enda Walsh, whose opera The Last Hotel, co-written with Donnacha Dennehy, is about to open at this year’s Dublin Theatre Festival. Walsh talks about growing up in north Dublin, being taught by Roddy Doyle, and about the highlights of his stage career, from first success Disco Pigs to the recent Ballyturk.
