Just in case I haven't persuaded you to watch Pitch Perfect yet, here's a video that should change all that.

Along with the excellent news that there will be a Pitch Perfect sequel arriving in 2015, today also saw the release of this music video for Anna Kendrick's When I'm Gone, more commonly known as Cups for reasons that will become apparent when you watch it. If they don't become apparent I don't quite know what to suggest, really.

Based on one of the most memorable scenes in the film and showing off the vocal talents of Anna Kendrick (who appears to have a music career now); I doubt it's all one shot once the cups start to move, but I sure as hell can't see the edits. Either way, it's an impressive piece of choreography that propels it beyond its current party trick status.
