The D.C. Asian Pacific American Film Festival celebrates its 10th anniversary this year, running tonight through Oct. 10. Opening the fest is 9500 Liberty, a documentary by directors Eric Byler and Annabel Park that explores the political and racial fallout from Prince William County’s aggressive illegal-immigration policy.

The film’s already earning plaudits: Last week, it took the Best Documentary Prize at the Charlotte Film Festival. Online tickets have already sold out, but a reserve of walk-up tickets are available, as well as a rush line that will begin releasing unclaimed tickets at 7:20 p.m. (There is also a drinks-and-nibbles afterparty at Rooftop Terrace; your stub or $10 cash gets you in.)
