My favorite movie is Iron Man II
this movie is about Tony Stark (the Iron Man), he fear that Tony's technology may fall into the wrong hands.
Tony's father to create a new source of energy. Justin Hammer want to know about the secret power in the iron man suit, so he try still it he have a partner name Ivan who has built his own weapon using stolen Stark blueprints, and want to destroy stark industries.
So Tony Stark as Iron Man Should fight for it, to keep the secret and defend the stark industries (his father industries)
