On Juneteenth, Stories of ‘Black Barbie’ and Jesse Owens’ Olympics Triumph, Netflix Streams ‘Dexter,’ PBS Turns to Nature

When a Black employee at Mattel asked the company’s co-founder Ruth Handler, “Why don’t we make a Barbie that looks like me?,” the stage was set for a breakthrough in representation resulting in the first Barbie of color in 1980. Black Barbie broadens out from the stories of three Black women within Mattel to reveal the history of Black dolls and the significance of children seeing themselves in the toys and dolls of their playtime.

One of the most celebrated figures in track and field history, Jesse Owens defied the racist Nazi policies of host country Germany and its leader Adolf Hitler when he competed at the 1936 Berlin Olympics, winning four gold medals (100-meter dash, long jump, 200-meter dash, 4×100-meter dash). A documentary from LeBron James and Maverick Carter’s SpringHill Company and narrated by Don Cheadle, Triumph frames Owens’ success against the racism of his times, including on the home front in his native U.S.

Showtime (or rather, Paramount+ with Showtime) is currently underway on Dexter: Original Sin, a prequel to this breakout thriller about Dexter Morgan (Michael C. Hall), a serial killer of serial killers and other villains who escaped justice. His ingenious cover occupation: blood spatter analyst for the Miami police. The gripping series’ eight-season run (2006-13) is now available for bingeing — minus the 2021-22 Dexter: New Blood sequel. The show peaked in its must-see fourth season, featuring John Lithgow’s Emmy-winning guest performance as Arthur Mitchell, aka the diabolical Trinity Killer. If this is your first encounter with Dexter, prepare to get hooked.

If you have sweated through or are about to endure an early eve-of-summer heat wave, welcome to climate change. A four-part docuseries travels to all seven continents of the Earth to witness extreme conditions of global warming, showing how the planet and its inhabitants are adapting and how conservations and scientists are planning for the future.

David E. Kelley (Presumed Innocent) teams with renowned chef/entrepreneur Andrew Zimmern for a three-part docuseries that looks to our vast watery depths — they call it aquaculture — for new ways to feed the planet and to preserve the oceans.

The episode also travels to Oahu for the restoration of an ancient fishpond and a Scottish isle that closed its waters to fishing to replenish the marine population.

Global explorer Josh Gates is back for his 13^th season, opening with a wide-ranging two-part premiere in which he joins a team digging in Egypt hoping to discover the lost tomb of Alexander the Great. Excavating in modern Alexandria has its risks, and when a water pump malfunctions, it could put the entire expedition at risk. Followed by the series premiere of Alien Encounters: Fact or Fiction (10/9c), in which UFO mavens Mitch Horowitz and Chrissy Newton assess claims of extraterrestrial encounters, including in the premiere, a geologist who’s found new evidence in debris at the legendary Roswell crash site and a mom whose alleged sighting of a mysterious orb left her with radiation burns.
