With the NFL playoffs in full swing, and no big blockbuster in sight, it was a relatively slow weekend at the box office. Both “The Bucket List” ($19.5 million) and “First Sunday” ($19 million) came in a virtual dead heat, followed by “Juno” ($14 million), “National Treasure 2” ($11.482 million), and “Alvin and the Chipmunks” ($9.1 million).

Radiohead’s “In Rainbows” locked down the top spot on the Billboard 200, despite all but giving away digital downloads on their website for months. Alicia Keys’s “As I Am” held the #2 spot, Mary J. Blige’s “Growing Pains” dropped from first to third, and Taylor Swift’s self-titled album matched its highest spot on the chart at #5 in its 63rd week on the charts. 

As anybody who watched football on Fox this weekend knows, last night saw the two-hour premiere of “Terminator: The Sarah Connor Chronicles,” to mixed reviews. Early reviews for “Cashmere Mafia,” like Bryan Kristopowitz’s at 411mania.com, have been somewhat less kind.

In book news, Michael Pollan’s “In Defense of Food” will break Stephen Colbert’s stranglehold on the bestseller list next week. “I Am America (And So Can You!)” drops to second, “An Inconvenient Book” from second to fourth, and “Clapton” from fifth to eighth.
