Spencer Cuppage concludes the festival, which combines classic films with live music, with a new piano score featuring jazz improvisation and a modern rhythm section to complement Buster Keaton’s superlative comedy from 1924. Stony-faced Keaton stars as a movie projectionist who imagines himself a famous sleuth literally inside the movies. Presented by the University of Idaho Department of History. (44 min) Tickets: $15 general admission, $10 student or $50 series pass.
