Some people have April 20th as their go-to uber-holiday for celebrating social activities, others have May 4th, and this year's X on the calendar is shaping up to be any fanboy's dream. Not only do we get Marvel's The Avengers in IMAX 3D, we will also be getting the brand new full-length The Dark Knight Rises trailer in IMAX.

This news comes from WB's private Exhibitor site, which confirms in their Placements section that this third trailer is arriving in theaters on May 4. It is not known when the trailer will hit the internet, but it promises to contain all-new footage. If you didn't have a reason to see Marvel's The Avengers in a theater before, you do know. May the 4th be with you!
