'We had maybe seven or eight camera tests we had to do, when it came to all the characters and for mine specifically it was, "How alien do we want Gamora to be?" she told Moviefone in a recent interview.

'And what I was thinking was, "She just needs to be pretty." And that's usually a thing that I don't think about with other characters that I play but for some reason because I was going to be green and I was going to be the lead girl, I just wanted teenage boys to find me attractive,' she admitted.

The star-studded film also features Benecio Del Toro as villain The Collector and Lee Pace as baddie Ronan and both were in Hollywood to view the blockbuster.

Bradley Cooper doesn't appear on screen but rather voices the computer animated mercenary Rocket Raccoon in the movie, and the actor happily signed autographs and took selfies with fans outside the event.

Glenn Close - who plays Rael, the commander of the Nova Corps, an intergalactic peace-keeping force cut a striking figure in a white trouser suit with lacy sleeves.

Guardians of the Galaxy will hit UK cinemas on August 1.
