Hollywood studios, fearing loss of revenue or premature leaking of confidential details, are inserting language in contracts that prohibits staff – even big-name stars – from using social-networking services such as Twitter to disclose details of projects.

Film stars Mike Myers and Cameron Diaz are lined up for a fourth Shrekmovie, set to appear next year. While it would be natural to expect that their contracts would forbid them from revealing plot details via Twitter or Facebook, some Internet sources, including and, have suggested that the stars have been forbidden to use Twitter at all.
