Wedding Wars (2006)

"His brother is out. His wedding is off. The war is on."

Ben, a slightly uptight man, ends up hiring his gay brother Shel, a party planner, to be his wedding planner. The two seem to be getting along famously, but then in the midst of planning, politics enters the fray. Ben is engaged to the governor's daughter, and the governor has taken a public stance against same sex marriage. Though his constituents seem to approve of his political agenda, Shel doesn't. And he shows his displeasure by walking off the job and going on strike for equal rights.
