Travel around the world without leaving the comforts of Williamsburg at this weekend’s Williamsburg International Film Festival. Films will be screened all day and night at the Knitting Factory and the brand-new indieScreen. The opening night gala on Thursday features performances by several local musicians, and culminates in the screening of Pool Party, a documentary featuring some of the coolest performances (MIA, Yeah Yeah Yeahs) that took place back when the Pool Parties were actually held in the McCarren Park Pool. Though there isn’t much detail available on their site regarding the other screenings, there’s a wide selection of shorts and full-length features being shown over the weekend. The films are broken into categories like “Animated Shorts,” “World Cinema Shorts,” “Narrative Feature Films,” and the perhaps most intriguingly named “Midnight Treats,” which includes “Jesus Comes to Town,” a short that manages to combine an underground poker name and the Second Coming.
