The Neighbor (2007)

Matthew Modine and Michèle Laroque star as two warring neighbors who discover that they might just be a match made in heaven during a date that was originally devised to send them on their separate ways. Christine (Laroque) is a powerful real estate developer who longs to acquire the apartment of her upstairs neighbor Jeff (Modine). Jeff is a businessman and artist who recently learned that his ex-wife is about to marry his ex-best friend. Recognizing that Christine wants him out of the building he has lived in for many years, Jeff agrees to move out if Christine will pose as his fiancée at his ex-wife's upcoming wedding. Christine realizes that this may be her only chance to rid herself of her longtime nemesis, and reluctantly agrees to take part in the ruse. Things get complicated, however, when Jeff and Christine step out onto the dance floor and lock lips during a slow dance. In the complicated aftermath of that confusing dance, Christine begins to rethink her renovation plans and Matthew realizes that he may have finally found the perfect mate.
