UPDATE: Dark Knight Rises Trailer - Leaked again, See it HERE

The trailer of the highly anticipated Dark Knight Rises Batman movie has leaked.

Now fans are blazing the Internet in search for that trailer, originally recorded by a fan at an early screening of the final Harry Potter movie, and posted by Huffington Post. The article and video link have since been pulled down, due to copyright infringement. But not before lucky viewers managed to salvage some details: Captioned text says Every hero has a journey, followed by Every journey has an end.

The final Harry Potter opens July 15. The Dark Knight trailer is believed to be attached to it.

Commissioner Gordon is said to be looking weary in a hospital bed, telling Bruce Wayne they are in this together.

Gordon begs for the return of Batman, and supervillain Bane is seen scaling the side of a building.
