Megan Mullally makes callousness into a fine art. As Karen on "Will & Grace," and now as Rosemary on "In the Motherhood," she pitches insults with an expert drop curve. Her snipes begin as straight-ahead affronts, before veering down into disdain, mild pity, and indifference. One minute she's scrutinizing a face; the next, she's looking right through it. Mullally is among the few comedians I can imagine having played the ferociously self-interested Elaine on "Seinfeld," other than Julia Louis-Dreyfus.
On "In the Motherhood," which premieres tonight at 8 on Channel 5, Mullally is in fine form, without Karen's shrill voice but with plenty of shoulder-shrugging attitude. I knew I'd love her on this single-camera comedy when Rosemary spontaneously decides to fake being pregnant so she can cut in line at the coffee shop. On a series that obsessively exalts the trials of being an upper-middle-class mother, Mullally brings on a welcome bit of subversion.
