We know Hollywood studios fake film reviews and movie ads. Now a sharp-eyed blog recently noticed some “strangely optimistic comments” from the same IP address within a 2-hour span after posting Relativity’s Mirror Mirror trailer. Turns out MovieMavericks.com found the exact same comments placed on many other blogs that posted the Mirror Mirror trailer. “The big question is who’s behind this ‘astroturfing’? Is it someone in Julia Robert’s camp? Tarsem Singh’s, Armie Hammer’s or Lily Collins’ people? Has Relativity Media hired some grey area marketing agency? Or is it simply a devoted fan?” the website asked. Oh puh-leeze: studios regularly hire trolls to post comments on the Internet.
