The Queen's cousin Lady Mary Colman reveals some royal secrets

An unaired episode of the documentary series shown earlier in the year about what life on the throne is really like. There are tales of US presidents breaking protocol, including one who got too familiar with the Queen on a state visit, plus a funny story about Her Majesty hiding in her garden from Romanian dictator Nicolae Ceausescu. But the most illuminating moments here come when we hear from royal insiders, who offer a glimpse of the real woman behind the crown.

Joined by Stephen Fry, Tony looks for the causes of his mental-health issues

Comedian Tony Slattery’s exuberant talent made the Whose Line Is It Anyway? regular a household name before a breakdown stalled his career. Now 60, Tony seeks expert advice to tackle his mental-health problems in this moving Horizon episode. Keen to find out if he has bipolar disorder, Tony meets his Peter’s Friends co-star Stephen Fry, who made a 2006 documentary on the subject. Digging at the roots of his problems, childhood trauma looms large but, encouragingly, there are a few flashes of the old Tony.

Suranne Jones as Doctor Foster

Best film to watch on TV tonight

A Walk in the Woods, 9pm, Film4

TV tonight A Walk in the Woods

Nick Nolte and Robert Redford star

Bill Bryson’s best-selling 1998 travel memoir about his foolhardy quest to trek the 2,200-mile Appalachian Trail gets turned into a breezy buddy comedy, with Robert Redford playing Bryson and Nick Nolte as the shambolic old friend who becomes his unlikely travelling companion. The duo don’t exactly blaze a new cinematic trail, but their bickering rapport throws up laughter and pathos, and the scenery is utterly splendid.
