Here’s what’s happening in the world of television for Sunday, July 5. All times are Eastern.
Top pick
Snowpiercer (TNT, 9 p.m.): This TV adaptation/spinoff of Bong Joon Ho’s 2013 post-apocalyptic film keeps barreling forward on its tracks, like a locomotive with no brakes (or like one that can never stop moving because the world has frozen over and there’s no way to survive outside). This week, it’s revolution time for Andre Layton (Daveed Diggs) and company.
