What do you get when an overrated artist discovers that his younger wife is not only stealing his work but also having an affair with a man who not only lives in his house but is also working on a dead train engine that the sentimental photographer wants to revive? A divorce from hell. The overrated photographer is O. Winston Link, the young wife is Conchita Mendoza, and the ordinary lover is Edward Hayes. The three sordid souls prove without a doubt that money is the root of all evil. (Northwest Film Forum, 1515 12th Ave, 267-5380. 7 and 9 pm, $5—$8.50.)
