Warner Bros also states that this is the FIRST world premiere, and that two more will take place afterwards in London and New York. The London premiere will take place on Tuesday, July 7th, and the New York City premiere will be the next day, on July 8th.

At the moment we do not know which of the stars will be attending the Japanese premiere; that information will be made public closer to the July date.
