I'm looking for a comedy movie where two(or three??) men using the dead body of a man, possibly their boss to hide the fact that he's dead and trying to find out how he is dead?
From what I recall, the dead man is a very rich businessman who is killed by his business partner/friend. The event happens at a beach house or place like that. The rich man just bought the house and an evening party was being held there.
I think he is killed during the party by injecting some poison into his body by a brutal assassin. The main characters play many pranks with the dead body to avoid others from knowing the fact that he's dead.
I think the timeline of the movie is between late 90's and early 2000's..
