Minus a preseason and most of its live audience, the National Football League attempts to begin a season amid the pandemic tonight with Houston at Kansas City (NBC, 8:20 p.m.). The stadium will be just 22 percent capacity but that still means 16,000 balancing beers and masks. There will likely also be attention on anthem protests, reflecting the summer’s racial reckoning. 

The week when Harry Belafonte took over for Johnny Carson in 1968 provided a showcase for art and activism in that moment, with guests that included Martin Luther King Jr., Robert Kennedy, Aretha Franklin and Sidney Poitier. It’s captured in the documentary “The Sit-In: Harry Belafonte Hosts the Tonight Show” (Peacock, streaming).

In the new musical series “Julie in the Phantoms” (Netflix, streaming), Madison Reyes plays a teen who gets in a band with the ghosts of guys who played in her mom’s band. Based on a hit Brazilian series, it’s from Kenny Ortega of “High School Musical” fame. 

Also meant for teens: “The Babysitter: Killer Queen” (Netflix, streaming), a sequel to the 2017 comedy horror film starring Judah Lewis, Robbie Amell and Bella Thorne. It’s directed and co-written by McG.
