A woman who found a copy of the New Moon vampire movie script in a trash bin has been invited to the movie’s premiere.

Beauty salon owner Casey Ray found two scripts, one for the vampire sequel New Moon and one for a different movie, titled Memoirs.

Instead of keeping hold of them, honest Casey handed them back to the movie studio.

In return she was invited to attend the movies’ premieres, her lawyer said.

Casey was waiting for her fiance to finish work when she spotted two scripts in a trash container.

She was outside a hotel where actors were staying during a St Louis shoot for the upcoming George Clooney movie, Up in the Air.

The Clooney movie includes actress Anna Kendrick, who is also in the Twilight vampire movie but it is unclear how the scripts wound up in the bin.

A spokeswoman for Kendrick, Lisa Perkins, said the actress wouldn’t have left scripts lying around.

When Casey found the scripts, she considered leaking them to the press but decided against it, said her lawyer, Al Watkins.

“My client didn’t really want to get paid,” he said but added that she was interested in hanging onto the scripts as collector’s items.

Instead Watkins helped her return them to Los Angeles-based Summit Entertainment LLC, the studio making the movies.

He said the studio invited Ray to premieres for the two film, and will certify the scripts as authentic after the movies are released.
