Reposting the information from the front page:
Ponyo on the Cliff by the Sea, Miyazaki's latest film is receving a one-night release in US theaters on the 14th. We'll be meeting up at the AMC Livonia 20. As soon as the '20 announces their showtimes for the 14th (which as of the 10th they still have not), we'll post exactly which screening we'll be attending. Available times permitting, we'll be aiming for somewhere around 7pm.
