The Landlord (1970)

At the age of 29, Elgar Enders (Beau Bridges) "runs away" from home. This running away consists of buying a building in a black ghetto in the Park Slope section of Brooklyn. Initially, his intention is to evict the black tenants and convert it into a posh flat. But Elgar is not one to be bound by yesterday's urges, and soon he has other thoughts on his mind. He's grown fond of the black tenants and particularly of Fanny (Diana Sands), the wife of a black radical; he's maybe fallen in love with Lanie (Marki Bey), a mixed race girl; he's lost interest in redecorating his home. Joyce (Lee Grant), his mother has not relinquished this interest and in one of the film's most hilarious sequences gives her MasterCharge card to Marge (Pearl Bailey), a black tenant and appoints her decorator.
