“Basketball County: In The Water,” a 51-minute documentary produced by Kevin Durant’s Thirty Five Ventures and Showtime, explores how and why Prince George’s County has evolved into a basketball hotbed. Filmmakers John Beckham and Jimmy Jenkins trace the area’s history and key basketball developments, noting that an extensive system of public parks and recreational centers provided safety and structure for a generation of athletes, including 25 NBA players, since 2000. The film airs Saturday at 9 p.m. on Showtime. #BasketballCounty (Photo by Katherine Frey/The Washington Post)
