Block-rocking beats

If you're a fan of electronic dance music, "What We Started" is a must-see, tracing EDM's roots to the Chicago and Detroit DJs who launched an underground movement that now fills stadiums. Beyond the history lesson, the film adds a personal element by focusing on jockeys from two generations: British turntable legend Carl Cox and youth Dutch phenom Martin Garrix.

The king of cool

As an actor, Steve McQueen was one feral cat. Abandoned by his father, neglected by his mother, dyslexic and partly deaf, he took up acting on a whim, making his way through sheer instinct and raw charisma. TCM celebrates him on Thursdays this month with 16 films, starting with the 1958 creature feature "The Blob" (7 p.m.) — for which McQueen was paid $3,000 — and John Sturges' epic western "The Magnificent Seven" (8:45 p.m.).

Mother superior

The great British actress Lesley Manville deserves to be better known by U.S. audiences, as her Oscar-nominated turn in "Phantom Thread" showed. Her bingeworthy sitcom "Mum" is a great excuse to get a free seven-day trial to BritBox, a streaming service for BBC and ITV shows. Manville plays an ever-buoyant middle-aged mother, coping with the recent death of her husband and the constant problems of her maddening family.

Now streaming at Britbox; episodes also air at 9 p.m. Fri & 9:30 p.m. Sat. on TPT, Ch. 2
