Katie Holmes and her new beau Tom Cruise could be heading to Australia for a working holiday.
Holmes, with her long brunette locks, is one of Hollywood's top candidates to play Wonder Woman in producer Joel Silver's film about the sexy superhero.
Silver has earmarked Australia as the likely shoot location for the big-budget project and Holmes says if the script is good, she might be interested in donning the red, white and blue costume and bullet-reflecting bracelets.
"I'd have to read it," Holmes told AAP in Los Angeles while promoting her new film, another big-budget comic adaptation, Batman Begins.
As a child growing up in Toledo, Ohio, Holmes said she idolised Wonder Woman, the superhero brought to life by actress Lynda Carter in the 1970s television series.
"I was part of the majority of little girls that loved Wonder Woman," Holmes said.
Hollywood-based Silver, whose films have made more than $US5 billion ($A6.6 billion) worldwide, says Australia is his favourite place to shoot. In recent years he made the Matrix trilogy, House of Wax and Ghost Ship in Australia.
Buffy the Vampire Slayer creator Joss Whedon will write the Wonder Woman script.
After her successful TV series Dawson's Creek and a number of strong performances in independent films such as Pieces of April, Holmes, 26, received her first taste of large-scale Hollywood film-making on Batman Begins.
Batman Begins reportedly cost $US120 million ($A159 million) to make and, with strong early reviews and a unique approach to the Batman genre by delving into the early life Bruce Wayne, the film will likely be one of the biggest hits of 2005.
Holmes, who plays a tough district attorney and love interest of the young Wayne, did not get to don a cape or costume, but the scale of the project impressed her.
"You have to have a good story in whatever medium you're involved in and this has a great story," Holmes, who surprised the entertainment world when she unveiled her romance with Cruise in late April, said of Batman Begins.
"It was exciting.
"The size of it, the sets, it was extraordinary."
Batman Begins opens in Australia on June 16.
