"Boardwalk Empire" (8 p.m., HBO) returns with more intrigue, more twists and more action than its shaky first season. Steve Buscemi is fine as usual, but keep your eye on Kelly Macdonald as the mistress who is more and more willing to turn the other way to provide for herself and her children. The grandmother of Carmela Soprano, perhaps?


For the first time ever, "The Colbert Report" (10:30 p.m., Comedy Central) will run for an hour, giving guest Radiohead a chance to perform songs from its recent release, "King of Limbs." Colbert notes that the appearance will give him a chance to garner some anti-corporate cred.


The excellent documentary "Catching Hell" (7 p.m., ESPN) looks at the horrors experienced by Chicago Cubs spectator Steve Bartman, who made the mistake of going for a foul ball in a playoff game and became one of the most hated figures in the Windy City. Bartman didn't cooperate for the movie, but you'll feel his pain. Unless you're a Cubbie fan.


Geniuses come in all shapes and sizes -- and accents. The new series "Rocky City Rednecks" (8 p.m., National Geographic Channel) introduces viewers to five Alabama men who like to make rockets, at least when they're not hunting, guzzling beer or cleaning up their trailer.


Night owls know that "Last Call With Carson Daly" (12:35 p.m., KARE, Ch. 11) is almost always a rerun. Not this time. Daly's got Slug and Ant of Minnesota hip-hop group Atmosphere on to celebrate, along with "Entourage" creator Doug Ellin and rapper Kreayshawn.
