Hi, I am Justin from Canada telling you how to make a Halloween costume of Scarface's Tony Montana.
If you want to be him from the beginning of the film, wear a Hawaiian shirt, white pants, and carry around a toy pistol. Wear fake blood on your face, along with a fake scar on your cheek.
If you are going for the later parts of the movie, do the same thing, except, wear a white suit, and carry around a machine gun.
Remember to shout lines from the movie like, when you go to the door, point the gun at them and say, "SAY ELLO (hello in a Cuban accent) TO MY LITTLE FRIEND!"
Thanks to Justin for this new idea.
