She Used To Be All That
Who’s Cashin’ a Cheque? Rachael Leigh Cook.
How Dependent Is The Ad On Her Celebrity? It's partially dependent on her celebrity, in that, like all the stars of Old Navy commercials, the fact that she's here is proof that the company considers her a D-lister (see also Jennifer Love Hewitt, Brad Goreski, George Takei, the stars of Christmas Vacation and Beverly Hills, 90210...).
On a Scale of 1 to 10, How Glamorous Is The Product She’s Promoting? In that Old Navy -- much as I may like it and shop there -- is a sub-Gap clothing retailer that sells shoddily made garments that generally don't survive more than ten washes, let's say it's a 3.
How Can We Humorously Connect This Spot To Her Best Known Role? "She must have bought the dress when she stopped in to get uniform khakis for her job at that falafel place."
Is This A Cheque Worth Cashin’? It might be if she got to play the Julie Hagerty role and do something that was at least slightly amusing or that played off her persona as a celebrity and thus positioned her for a career revival of some sort. But she just walks down the stairs, has no lines, and isn't identified by name, so if you were playing Letterpress during the commercial break, you didn't even know she was in it. This is a terrible move. (But, to be honest, a pretty cute dress.)
