Some people at DreamWorks were sent home today because of a bomb threat at the studio. They later discovered it was just the trailer to the next installment of Shrek.
Seriously though, studio employees are writing about the bomb threat on Twitter.
UPDATE: According to Arthurk192, “Authorities have determined that the package was not a bomb. It was, in fact, a gift from overseas, officials said.”
UPDATE 2: The Glendale News Press has an article about the suspicious package at DreamWorks.
