When your lead actress' new movie scores $155 million on opening weekend, it's probably best to capitalize on promoting her next feature.  Jennifer Lawrence is the woman of the hour after The Hunger Games, and Relativity is capitalizing on that hour by releasing the first trailer for her new movie House at the End of the Street.  Lawrence plays a young woman who moves with her mother to a new house that's next door to the home where a grizzly murder took place years before.  The trailer plays the major beats of the movie in reverse order, which makes the plot intriguing, but also confusing.  After watching it, I don't know if the entire movie is in reverse order (a la Memento) or just the trailer.  I'm fairly certain it's only the trailer, but audiences may be left wondering if they're seeing Memento but with horror and a sweaty, scared Jennifer Lawrence.

Hit the jump to check out the trailer.  The film also stars Elisabeth Shue, Max Thieriot, and Gil Bellows.  House at the End of the Street opens September 21st.

Here's the official synopsis for House at the End of the Street:

Seeking a fresh start, newly divorced Sarah (Oscar®-nominee Elisabeth Shue; Leaving Las Vegas, Piranha 3D) and her daughter Elissa (Oscar®-nominee Jennifer Lawrence; X-Men: First Class, Winter’s Bone) find the house of their dreams in a small, upscale, rural town. But when startling and unexplainable events begin to happen, Sarah and Elissa learn the town is in the shadows of a chilling secret. Years earlier, in the house next door, a daughter killed her parents in their beds, and disappeared - leaving only a brother, Ryan (Max Thieriot, My Soul to Take), as the sole survivor.  Against Sarah's wishes, Elissa begins a relationship with the reclusive Ryan - and the closer they get, the deeper they're all pulled into a mystery more dangerous than they ever imagined.
