Word from /Film and FirstShowing suggests Warner Bros. will be attaching a 6 minute prologue from The Dark Knight Rises to Mission: Impossible Ghost Protocol when it is released in IMAX on December 16 (5 days before the general release on December 21).
Warner Bros. did a similar thing with The Dark Knight in 2007 when it attached The Joker opening sequence to I Am Legend on IMAX screens. No word yet on what the 6 minute prologue will contain (probably some Bane and/or Catwoman), but i’m going to try and avoid it. I want to see the whole movie spoiler-free next July, and seeing 6 minutes of it (plus all the trailers) months before hand will probably ruin that.
Warner Bros. has yet to confirm this, but with multiple sites hearing the same thing it’s likely to happen.
The Dark Knight Rises is set for release on July 20th, 2012. Christian Bale, Michael Caine, Gary Oldman and Morgan Freeman will reprise their roles alongside Anne Hathaway (Catwoman), Tom Hardy (Bane), Marion Cotillard and Joseph Gordon-Levitt.
