The Imax release of Harry Potter and the Half-Blood Prince will open fourteen days after the movie premieres in regular theaters, reportedly owing to Paramount's deal with Imax to show Transformers: Revenge of the Fallen on their screens exclusively for four weeks. But there's good news, too! According to MichaelBay.com, the Imax version of T2 will be a "slightly longer cut with more robot fighting." [Ace Showbiz, Michael Bay via Playlist]
