KATIE, THE EVER-READY BUNNY: Despite a Sunday morning that began with a five-hour, 29-minute and 58-second run in the New York City Marathon, Katie Holmes truly tested the outer limits of endurance by attending a screening of "Lions for Lambs" at MoMA that evening. Looking none the worse for wear in an all-black Bottega Veneta ensemble — and showing up at 7 p.m. on the dot for the screening — she dutifully posed for photographs and signed autographs alongside husband Tom Cruise, who costars in the political drama as a rising GOP senator. (Cruise also coheads, with Paula Wagner, United Artists, the label distributing "Lions," which is the very first project under UA's new leadership.) The film also stars Meryl Streep and Robert Redford (who did double duty as director).

After Cruise and Holmes braved the paparazzi, Redford greeted a crowd that included Barry Diller and Diane von Furstenberg, David Lauren and Lauren Bush and Kevin Bacon and Kyra Sedgwick, by explaining his latest movie is intended to explore "the gray areas" of the current situation in Iraq, which has been painted as "black and white, or red and blue."

When the final credits rolled, Holmes and Cruise made a dash for it, skipping an after party that might've been too much for the marathoner to tackle in one day. But the running around may be far from over: Next up for the film is a planned campaign stop in Washington, where "Lions" was to be screened for a bipartisan crowd of senators on Monday.
