He discovers the Mandarin is a creation of Aldrich Killian seeking revenge against Stark. Killian's plan is to kidnap the President, but Stark works to defeat Killian and rescue Pepper Potts, saving the President. The film was a major box office success, grossing over $1 billion due to extensive marketing using social media and other techniques not available for earlier Iron Man films.
