A cake was delivered to the Baltimore Sun's offices one day a few months back. It was a seven-layer cake from Caroline's Cakes in Annapolis. Gosh, was it good. I remember having posted about how good it was somewhere -- Twitter or Facebook or here? -- but now I can't find it.
By most accounts, the cake gives a layered performance in the film.
Also, you should read Michael Sragow's blog post on a review of The Help that aired on MsNBC that got under his skin.
