Gwyneth Paltrow is Pepper Potts
Fun fact: Tony Stark made the Mark 1616 Iron Man suit specifically for Pepper to use in an emergency. Her suit came equipped with the AI Jarvis to assist her. After a little practice she became a part time super hero in her own right, under the name Rescue. She sometimes filled in when Iron Man wasn't around, and has teamed up with both Iron Man and War Machine. Eventually the AI Jarvis fell in love with pepper and ended up kidnapping her. Iron Man and Pepper had to destroy the armor to end the threat, and thus ended Rescue's super hero career.
