Warner Bros. Pictures is under fire for
an electronically enhanced photo of "Harry Potter" star Emma Watson advertising the newest installment in the series.

In the new poster for the version of the film for Imax 3D cinemas, the 17-year-old actress, who plays 15-year-old Hermione Granger, appears to have had her bust enhanced, The Mail on Sunday reported.

A similar photo in ads for the regular film version of "Harry Potter And The Order Of The Phoenix" is un-altered.

The editor of a Harry Potter fan Web site, Melissa Anelli, said hundreds of fans have already posted angry messages.

"Emma Watson is playing a 15-year-old girl, and she herself is under 18," she said. "I get the full heebie jeebies thinking about the person who sat there thinking: 'Now, if we cinch her waist a bit, and inflate her bust a bit, and give her some dramatic lighting and more blonde hair, this would be a much better picture.'"

Warner Bros. released a statement saying the enhanced image was not approved.

"This is not an official poster. Unfortunately this image was accidentally posted on the Imax website. The mistake was promptly rectified and the image taken down," the statement said.
