Aniston's closest attempt at seduction? After being locked in a car trunk by Butler and then handcuffed to a bed, the actress dons a slinky black mini to try to get her way out of a jam. However, the plan backfires when he notices her reaching for his gun.

The romantic comedy, filmed last summer in New York City, is expected to hit theaters next March.
