Walt Disney today said it took "appropriate action" against employees at its Paris theme park who were caught simulating sex while dressed as Disney characters in a digital video that has received wide attention on the internet.

Disney would not say whether it had dismissed any of the costumed employees featured in the grainy video, which appears to have been shot with a hidden camera at a backstage dressing room at Disneyland Resort Paris.

"The behavior shown on the video is unacceptable and inexcusable," Disney said in a statement.

"The video was taken in the backstage area not accessible to guests. Appropriate action has been taken to deal with the cast members involved."

The video shows Minnie Mouse struggling to free herself as she is grabbed from behind by Goofy and then a giant snowman.

Later, Mickey Mouse simulates sex with the snowman and Goofy does the same with either Chip or Dale, the chipmunks, as laughter is heard on the tape.

The tape is described on the Internet as the "Mouse Orgy".
