both movies portray the daily life of contract killers in a sarcastic and human way. Killers are also humans. Killers cannot live the way others do because of the guilt weighing on their shoulders.
Suicide is the starting point for both these movies (they also shares the same main actress!) and a disfunctional love story sprouts from both the encounters!
Both stories feature unconventional heroes, are in rather absurd situations, and feature a twisted sense of humor. They are both great comedies with brilliant actors!
