Terry Bradshaw, Christopher Gorham, Charisma Carpenter, and Nicholas Brendon have signed on to star in the comedy, Relative Chaos for the ABC Family Channel.

The movie centers on a family reunion where Will Gilbert (Bradshaw) holds a weeklong competition among his kids, Dil (Gorham), Gil (Brendon) and Lil (Jenn Robertson); the winner takes home the family trophy, the Gilbert Cup. The Hollywood Reporter says Dil doesn't want to participate this time, but his new girlfriend (Carpenter), a highly driven business consultant, has vowed that this will be his year, even if it kills him.

Shooting is set to begin this month in Halifax, Nova Scotia; check out Relative Chaos which is scheduled to premiere in September on ABC Family.
