Anonymous visitor: The trailer [of Harry Potter And The Half Blood Prince] comes out before the movie get smart. I know for a fact because i have a friend who brought who works at a movie theater and showed it to me, the movie looks so good.
I’m inclined to believe this visitor because it would confirm a rumor which has been on the web. So maybe time to pre-reserve your ticket for Get Smart if you’re a fan of Harry Potter.
Update as of June 21: Seems Warner Bros. change their mind: according to the first reports the trailer of Harry Potter 6 The Half Blood Prince has not been shown in front of Get Smart….
Update as of July 11: IMAX Corporation has confirmed that there will be a SHORT, 15 second trailer for Harry Potter and the Half Blood Prince prior to The Dark Knight !!!
Update as of July 19: A 15-second teaser of Harry Potter 6 is now available, but don’t expect too much… Head to the link below to watch it:
We hope that in 2 weeks a full length trailer of Harry Potter and the Half Blood Prince will be shown in front of the Mummy 3.
