Searching for movie title of a comedy: The plot takes place, I believe,in an little Irish village where one of the villagers wins the lotto, then dies. The whole village becomes involved in a plot for one of the villagers to take on the dead person's identity in order to take claim to the winning lotto and money.

Sounds like Waking Ned Devine (http://www.imdb.com/title/tt0166396/).
