Pick of the week: “A Very Murray Christmas” — Wes Anderson movies excepted, can Bill Murray just play Bill Murray from now on? While his last couple of movies (“Rock the Casbah,” “St. Vincent”) were underwhelming, Murray is his charming, funny self in this affectionate goof on old celebrity Christmas specials, playing himself snowbound in New York’s Carlyle Hotel and putting on an ad hoc holiday special with the help of Jenny Lewis, Jason Schwartzman, Maya Rudolph — and, oh yeah, Miley Cyrus and George Clooney. It’s a smooth, silly, after-the-kids-are-tucked-in-their-beds kind of holiday special.
