As some were predicting, The Dark Knight Rises teaser trailer will reportedly play before Harry Potter 7 part 2. Superhero Hype! has it from a trusted source that the teaser will be one minute and 33 seconds long, will play in 2D, 3D, and IMAX. No word on the content beyond that.
If true, this pretty much guarantees that Harry Potter and The Deathly Hallows Part 2 will be the biggest moneymaker this summer.
