Catherine Keener has performed a number of noteworthy roles since her cameo as yet another entry in Jerry Seinfeld’s inexplicably long list of girlfriends, including seminal parts in the excellent Being John Malkovich, for which she was nominated for an Oscar, and the not-quite-so-excellent The 40 Year Old Virgin. In the world of Jerry, George, Kramer and Elaine, however, the attractive actress plays an artist who not only paints “that” portrait of Cosmo, but simultaneously manages to inadvertently dupe the always money conscious George into buying an atrocious painting of hers. A classic episode (“The Letter”), with a classic celebrity-to-be cameo.
