Warner Bros. has alerted members of the writers branch of the Academy of Motion Picture Arts & Sciences that it had sent out the wrong version of the “J. Edgar” script by Dustin Lance Black.

In a missive sent out Friday, the studio said it had mistakenly sent out the continuity draft — not written by Black — to the 163 members who had requested the shooting script. It apologized and attached Black’s shooting script.

“The language in this continuity draft was not written by Mr. Black and was meant as a reference tool for post-production only,” the message said. “Please discard it.”

The writers branch comprises about 8% of the Academy’s voting members with 376 out of 5,783.
