Inspired by a true story, this 2018 Clint Eastwood movie (which he directs as well as stars in) tells of a 90-year-old man who becomes a drug mule crossing the border with illegal substances – at first unwittingly, then willingly, with his advanced age providing the perfect cover. Bradley Cooper plays the agent eventually on his tail, and Eastwood’s real-life daughter, Alison Eastwood, is one of his other co-stars.

David Attenborough narrates this continuing series, which is all I need to continue recommending it. Tonight’s installment focuses on rare, treasured creatures – and boy, in TV terms, Attenborough certainly qualifies as one of those. He's been doing nature documentaries for TV since the 1950s, and is now 93 years old – two years older than Clint Eastwood’s character in The Mule.
