Speaking of Fargo, I came across Kirk Demarais' site, and paintings, via Jeffrey Wells' Hollywood Elsewhere column. Kirk has a few other cinematic family portraits — the Torrances, the Freelings — but for obvious reasons this one hit home:

Thoughts on other cinematic family portraits Demarais should do? I like the happy family portrait before the tragedy, which is why the Griswolds doesn't work for me. The family should also be middle-class, because such paintings are (or were) middle-class staples, which lets out, say, the Corleones.

The Jarretts from Ordinary People maybe? The Burnhams from American Beauty? The Hoovers of Little Miss Sunshine?
