LOVELL — The family of Jonathan Demme, the late, Oscar-winning director of films such as “The Silence of the Lambs” and “Philadelphia,” has donated his 1967 ski boat to next month’s Lovell Historical Society annual auction – an unusual donation with an unusual twist. The boat’s never been in water outside Kezar Lake. Kezar Lake Marina co-owner Lee Conary said Demme, who died last year, used to take the Correct Craft Mustang out with his kids, pulling them around on inner tubes.
