Update: The studio (and contract clause) mentioned in this blog item, DreamWorks Studios,  is not affiliated with DreamWorks Animation that makes the "Shrek" films. Also, the contract clause for DreamWorks Studios is for writers releasing non-public information and  is not a ban on talent using Twitter. Cameron Diaz and Mike Myers have not been banned from Twitter. Thank God!
