The Joneses (2009)

Demi Moore and David Duchovny star as a seemingly perfect couple who, along with their equally perfect teenagers (Amber Heard and Ben Hollingsworth) move into an upscale gated community. The Joneses have better goods and game than any other family in town. The only problem is they're not a family - they are employees of a stealth marketing organization, and they know how to make everyone else want what they've got.
