Among the second week’s highlights are an encore screening of the Buppie romance Medicine for Melancholy (recently a hit at Northwest Film Forum). The Oscar-nominated documentary Trouble the Water recounts what happened to those unable to get out of New Orleans when Hurricane Katrina struck. A more cheerful doc follows a 90-year-old Pennsylvania woman on her quest to vote for Barack Obama. The fest closes with a documentary tribute the great salsa star Celia Cruz.
