Which celebrity shillers should quit their day job?

As awards season approaches and "serious films" (i.e., Rendition, Things We Lost in the Fire, Martian Child, etc.) hit the theaters, Radar examines the stars who are shining brighter off the big screen and hitting pay dirt in an advertisement near you. Below, comparisons of critical responses to their real "work" and their part-time shillery.

Scarlett Johansson

As an actress, ScarJo peaked with 2003's Lost In Translation. Her first collaboration with Woody Allen, Match Point, wasn't bad either. But since then, it's been a slow slide downhill. Key low points along the way include a Michael Bay movie, The Island, and this year's The Nanny Diaries. Luckily, although her acting career may be petering out, Miss Jo has a string of lucrative endorsements. She followed up her gig as Coppola ingénue with work for Calvin Klein fragrance, L'Oréal, Reebok, and Louis Vuitton.

CRITICAL COMMENTS
"Scarlett Johansson channels Grace Kelly and Marilyn Monroe."
—jossip.com on her Louis Vuitton ads

"Scarlett Johansson, trying to give the material a plausible emotional center, looks merely confused."
—David Denby, The New Yorker, on her work in The Nanny Diaries

FINAL JUDGEMENT
She's a pretty face and a hot bod, for sure, but lately it's hard to buy what she's selling in her big-screen roles.
