Kissin' Cousins

So much mayhem ensues that it takes two Elvises to handle it! In his only dual role, Presley is both of the titular cousins: a redneck moonshiner, and an emissary sent by the Army to convince the hillbillies on Tatum Mountain to allow the government to use half their land as a missile launch site. The locals' antipathy for Uncle Sam provides a convenient opportunity for a fistfight between the dueling Elvises. (official distributor synopsis)
