One of the documentaries considered for an Oscar on Sunday, Feb.  27 was Waste Land. The film documents a project to turn trash from a landfill on the outskirts of the Rio de Janeiro into art – and perhaps create social change as well. Waste Land screens Friday, Mar.11 at Northwestern University’s Block Cinema in Evanston. Eight Forty-Eight film critic Christy LeMaster spoke with Alison Cuddy about the film, she began with a little background, and the filmmaker’s approach.

LeMaster and Cuddy also reviewed the “mumblecore” mystery-comedy, Cold Weather.
