after watching this movie in my russian class, i got to thinking, the general plot points of both this movie and GTA4 are really similar.
-main character is of russian/east european descent
-main character is an ex-military person
-MC moves to a new city to live with brother to make a better life
-Brother screws up these plans by forcing the MC to become a killer/criminal again
-MC has to kill a lot of people to keep himself and brother safe.
