Gwyneth Paltrow says that Pepper Potts' relationship with Tony Stark has developed a lot throughout the movie but Iron Man 3 sees them more on an equal pegging.
Paltrow is back as Potts in Iron Man 3 and she has settled into her role as CEO of Stark Enterprises and this character goes on the biggest journey in this new movie.
In this video Paltrow says that Potts has really stepped into her power both personally and professionally.
But the actress says that she loved the physical aspect of the movie because she has never done many stunts before.
Iron Man 3 is the first stand alone Iron Man movie since 2010 - although Paltrow did briefly appear in Avengers Assemble last summer.
The movie sees the Oscar winning actress team up with director Shane Black for the first time as he took over the helm from Jon Favreau.
