With its healthy global box-office take of almost $350 million so far, Thor is anything but a bomb — but apparently, no one told the population of Ann Arbor, Michigan. Automobile magazine reports that as a tie-in to the film, promotional partner Acura sent out briefcase-shaped press kits that were marked with “detonation switches†and filled with vials of blue liquid. The objects were supposed to be mock “test kits†for agents of S.H.I.E.L.D., the government agency spanning Marvel movies like Thor and Iron Man, but despite the obvious branding, a test kit tossed in the garbage prompted bomb-fearing Ann Arbor police to call in U.S. Marshals and agents from the FBI and ATF. Alas, it was all for naught, and some bomb defuser’s dream of coolly walking away from an explosion in slow-motion will remain just that: a dream. [Automobile Magazine via AV Club]
