Thor has gone from being one of Marvels least fashionable properties to one of the linchpins of the Cinematic Universe, with Marvel Studios doing an excellent job at making the character not only relevant, but cool again. Though comparatively pretty water-tight when it comes to mistakes, a few do pop up in the first Thor film. One example that annoys only those with a keen eye for goofs is when a SHIELD monitor reads perimiter when of course the correct spelling is perimeter. Either SHIELDs training isnt what it used to be, or someone on set skipped coffee that morning. It wasn't the only SHIELD-related goof to ruin an otherwise cool scene either. As a group of hapless men attempt to pull Thor's hammer Mjolnir out of its crater in front of curious and confused onlookers, an agent of SHIELD can be seen pulling up on the hilltop about 50 yards away in an SUV. When the agent gets out of his vehicle and we see him looking into the crater, he is at least half a mile back from where he was in the previous shot.
