Mad Men Sunday, 10 p.m., AMC
Will Sally expose Don’s affair? Will Peggy finally get fed up and leave? Will Bob Benson ever stop smiling? Will Don drink, smoke, brood, and make poor decisions? Well we can certainly count on that last thing as season 6 of “Mad Men” comes to a close. It’s been a mixed bag of episodes with a lot of individually excellent and memorable moments and great acting all around, so it will be interesting to see how Matt Weiner and the writers tie it all up.
Crossing Lines Sunday, 9 p.m., NBC
William Fichtner is a terrific character actor who has done memorable work in many films (“Crash,” “Date Night”) and on television (“Prison Break,” “Empire Falls”). He’s also no stranger to the stage, having trod the boards at the Williamstown Theatre Festival in Western Mass. Is that enough to get me to watch what looks like yet another crime procedural — this one about “a unit mandated by the International Criminal Court (ICC) to investigate cross-border crimes and ultimately bring global criminals to justice”? Probably not. But throwing in Donald Sutherland guarantees I’ll at least give it a shot.
