Gwyneth Paltrow reportedly made herself unpopular while filming the new Iron Man sequel.

The actress recently completed filming the upcoming action movie, due for release around May 2010, and was "not friendly" to any of the cast and crew, according to FOX411.

A source admitted that some crewmembers hoped that her character would be recast - or even killed off - but are now resigned to the fact that she will remain in the role of Pepper Potts should a third film be commissioned.

The insider said: "Gwyneth is extremely cool at work. She's just a step above professional, too snobby. Gwyneth is not friendly to anyone, and tends to make people feel awkward and uncomfortable.

"She wasn't outright rude to Scarlett [Johansson], she just didn't ever speak to her. Gwyneth went out of her way to avoid Scarlett, and they had zero contact, at Gwyneth's choosing."
