We now know of two The Other Boleyn Girl premieres: a Royal Premiere in London, England on the evening of February 19, 2008 and another one in Vancouver, Canada on February 25, 2008 at 7 pm. For some information about the Royal Premiere, check out CTBF.co.uk. For Vancouver premiere, you can win passes at 95crave.com. Good luck! No word whether or not Scarlett will be in attendance.
