Civil disobedience

“The Avengers” aren’t the only ones battling a Civil War. “DC’s Legends of Tomorrow” try to one-up their Marvel counterparts by zipping back to 1863, where they face Confederate soldiers who have turned into zombies. Even worse, these new opponents think Iron Man is 10 times more charismatic than Hawkgirl.

Songs in the Keys of life

At least one judge on “The Voice” is aching to show off her own vocal chops. “Alicia Here in Times Square” gives the talented Alicia Keys a chance to get into an Empire State of Mind with numbers from her new album, “Here,” and a guest appearance by Jay Z. The only thing better: if Bob Dylan were to name-drop her in his Nobel Prize acceptance speech, just as he did in his 2006 song “Thunder on the Mountain.”

Déjà vu

Bill Murray, the most recent recipient of the Mark Twain Prize for American Humor, has been someone to keep an eye on since the 1970s, but he didn’t really register as a formidable actor until 1993’s “Groundhog Day.” Word has it that Murray and director Harold Ramis battled over the direction of the film, but it’s hard to argue with the final product, one you can enjoy over and over and over again.
