The opening scene of Damien Chazelle's Babylon (Paramount, 12.23) is set in a hilly section of Bel Air circa 1926. Except it doesn't look right. For 80 or 90 years Bel Air has been a flush and fragrant oasis for the super-wealthy, but in the mid '20s, according to Babylon, it was fairly dry and barren and desert-like -- no trees, no bushes, no grass and definitely no golf course. Almost Lawrence of Bel Air.
