The Screen Actors Guild sent a warning to members Sunday that studio screeners sent to them in connection with the upcoming SAG Awards "may not be sold, transferred to a third party or used for any other purpose." If it is discovered that any of them have been so used, the guild said, members could be subject to criminal prosecution or civil liability. Moreover, it warned, "SAG will also review any alleged violation of these restrictions for possible charges of conduct unbecoming a member."
