Tony Stark is a character one falls in love with as time goes. In the first, he is a cinematic play boy - rich and handsome, genius in science and a business man.
This movie is the first of the Iron Man series with Stark being shown as the newly appointed CEO of the Stark Industries that manufacture the weapons to wage wars and bring peace. He is in Afghanistan modelling one of the missiles that his company has made. He is ambushed while returning and taken for imprisonment in a cave.
He meets a scientist from Gulmira in the cave and asked to build a missile that will counter attack the weapon he displayed earlier. Stark manages to create a artificial heart for himself and an iron armour that helps him escape from the cave and the troops that captured him.
Once Stark is back in the US, he learns that his own and his father's partner Obadiah Stane is involved with the terrorist troops. He avenges Obadiah who also develops a iron man kind of armour with the help of his engineers. In all this mean time, he falls in love with his present assistant and future wife Pepper Pots.
The final battle between these two is a great watch. The arc reactor phenomenon is fantastic scene. The plot is curiosity grabber. Robert Downey Jr is the man to look for in this one and all the next movies to come for 10 years.
