Though I haven't yet learned the answer to the second question, it turns out that Madonna and Hutz are quite the close collaborators these days. Hutz, who fronts the gypsy-punk Bordello and also stars in Everything Is Illuminated, is working on Madonna's forthcoming short film, Filth & Wisdom.
In addition to acting in the film, Hutz contributed to the script and will lend his music to soundtrack for the movie, which is expected to debut next year at Sundance. Apparently, Madonna really likes Gogol Bordello, because the band also joined her onstage at Live Earth in London for a polka-infused rendition of "La Isla Bonita." It's really a fun performance to watch, so check out the video (thanks, Pitchfork) when you read more
