No one in the movies manages a look of stupefaction and bliss the way Anna Faris does. I've seen Johnny Depp and Cameron Diaz attempt it, but Faris seems possessed by the shock of anticipation. Shelley, the blond Playboy Mansion dolt Faris plays in "The House Bunny," has a birthday blowout where an obscenely giant cake is wheeled her way. She looks up at it, and her awe practically glows: I'm gonna have to eat the whole thing!
But it's hard to build an entire comedy out of that face, and the men and women who've cobbled together "The House Bunny" give up trying. Faris plays her usual lunatic-idiot. This time her hard-working caricature inches closer to the proportions of an actual human being. Shelley finds herself evicted from the Mansion. The goodbye letter cites her old age. (She just turned 27, which someone explains is "59 in Bunny years.") She drifts for a few scenes until she ends up at a sorority whose unpopularity has put it on the college's endangered list.
