The movie that led me to want to become a filmmaker is the movie Terminator and its starring actor Arnold.
Ever since seeing that movie and the way James Cameron focused the vision of the Terminator being unstoppable and indestructible. Showing how insane but possible as such an event like machines taking over the world could be. Plus simply how awesome it was seeing this big musclebound dude just going around on a harley and just shooting its victims in the face. Even going as far to kill its target inspite of being punched, stabbed, shot, bombed, burned, legs blown, and finally going as far as getting itself crushed...but still wanting to go until its core was completely flattened under another machine!
After seeing all of that and the other movies after it. It just hit me and made me think "I so gotta get involved" lol.
