Actress Olivia Munn fears she'll never land her dream role as Wonder Woman because of her Chinese background. The Asian-American star, who appeared in Iron Man 2 and is a self-confessed comic book geek, would love to play the all-American heroine but she fears her heritage stands in her way. The Newsroom star says, "It would be great if the producers could make Wonder Woman an Asian-American, but that's probably not what they would do. I don't know a lot of Asian-American women who are getting great opportunities yet, and the other actresses (up for the role) are probably really famous, and Hollywood tends to go for the girls who are already in the big movies." Munn, who authored the book Suck It, Wonder Woman!: The Misadventures Of A Hollywood Geek, tells Press Association she once dressed up as Wonder Woman to attend the Comic-Con convention in San Diego, California, but admits that was a bad idea: "It's not comfortable to dress up in front of all those people. Costumes for superheroes... are always very skimpy, so it's not something that you want to wear with a lot of people around you."
