The Big White (2005)

Everybody wants out of Alaska. Paul Barnell (Robin Williams) is tired of his business and the cold. And he desperately wants to take his crazy wife Margaret (Holly Hunter) on a second honeymoon in a warmer climate. So when Paul finds a dead body in a dumpster, he gets the idea to claim it's his brother, so he can collect on the life insurance policy. But Ted (Giovanni Ribisi), an agent for the insurance company suspects something's wrong and starts investigating. Ted is hoping to crack the case, earn a promotion and get out of Alaska. Then things really get complicated. Paul's real, live brother Ray (Woody Harrelson) comes back to town, and the 'owners' of the dead body want their corpse back.
