6-Minute Dark Knight Rises Prologue with Mission: Impossible?

/Film has posted an interesting rumor that Warner Bros. Pictures is planning on showing a six-minute prologue for The Dark Knight Rises with Paramount Pictures' early release of Mission: Impossible – Ghost Protocol in IMAX theaters on December 16 (the film has its general release on Dec. 21).

It would be a similar situation as The Dark Knight, from which Warner Bros. attached the opening sequence to the Will Smith hit I Am Legend in IMAX theaters in December of 2007.

We should be seeing a press release about this soon if this is indeed confirmed. We're also assuming a new trailer for The Dark Knight Rises will be attached to Warner Bros.' own Sherlock Holmes: A Game of Shadows on Dec. 21, but that also is not confirmed yet.

The Dark Knight Rises opens in theaters on July 20, 2012.
