AETN and KUAR will host a free screening of the new documentary “Medora” tonight at 6:30 p.m. at the William F. Laman Library. Directed by Andrew Cohn and Davy Rothbart (of FOUND magazine and “This American Life”), the film focuses on small, rural Indiana town called Medora and its high school basketball team, last-place in the state. The Village Voice called it a “stellar, incisive slice-of-life doc,” and it looks gorgeously shot and downbeat and pretty interesting.
