Gwyneth Paltrow Talks About Her "Sexually Charged" Scenes In 'Iron Man'

Gwyneth Paltrow's scenes with her 'Iron Man' co-star Robert Downey Jr. were "sexually charged".

The 35-year-old actress - who has two children with her Coldplay frontman husband Chris Martin - admits she enjoyed the on-screen chemistry she had with Robert.

Gwyneth, who plays Robert's character Tony Stark's devoted assistant Virginia 'Pepper' Potts in the superhero movie, said: "Robert kept me on my toes and kept our on-screen relationship sexually charged. Sometimes I have had to work with people I have had zero chemistry with, and it's like pulling teeth."

"Because sometimes it's just not there and when it is there, it's like flying. It feels like you can do anything, and when it's not there it's a struggle. I've had that quite a few times."

Gwyneth also revealed she jumped at the chance to star in a big budget movie, and would not rule out doing more blockbuster films in the future.

She added to FOX News: "Everyone has the wrong idea of me. I have absolutely nothing against doing a movie with all kinds of special effects."

"As long as the people involved are going to make me better at what I do, I'll do any genre. Maybe not porn, but anything else!"
