The Leaky Cauldron is reporting that the British Board of Film Classification (similar to the MPAA in the United States) has updated their website to list the running time and rating for Harry Potter and the Half-Blood Prince.

The running time is listed as “153m 19s,” with a content rating of “12A.” (The MPAA lists the film as “PG.”)

In other Harry Potter news, the IMAX release of Half-Blood Prince has been delayed two weeks. The movie will still be shown in standard-format theaters on the same date of July 15, 2009.
