Producers include Selma director Ava DuVernay, Greg Berlanti, and Philadelphia’s Kevin Hooks. 8 p.m. Sunday, April 28, CBS.

Game of Thrones. You know all that singing and knighting and night-before-battle merriment last Sunday? I think that’s over. The longest episode of the six-episode season is expected to clock in at one hour, 22 minutes, after which I’m afraid the army of the dead might have new recruits. Also: If the Winterfell crypt turns out to be a safe space, my years on the TV night watch will have been wasted. 9 p.m. Sunday, April 28, HBO.

The 100. The post-apocalyptic drama about youthful survivors trying to re-establish life on Earth launches its sixth season and has already been renewed for a seventh. Which means, I suppose, that it hasn’t run out of characters to kill. Yet. 9 p.m. Tuesday, April 30, CW.
