Goofs

(at around 1h 12 mins) Four goofs when fighting at the MRI-scanner:1: The window where the gas cylinder shoots through has no metal mesh in front of it, and there is no door at the entrance of the scan room. Both are essential parts to complete the Faraday cage the scanner has to be in. This to prevent magnetic or RF-interference from getting in or out of the scan room.2: The magnetic field can't be switched back on instantaneously after hitting the emergency magnetic field release (quench) button. It takes at least a day and several thousand liters of helium to be able to ramp the field back up after a quench.3: Almost all MRI scanners have active magnetic shielding to minimize the magnetic field around the scanner. This would make it impossible for the field to have enough strength to pull John back towards the scanner when he stand as far away from the scanner as he does at the end of the scene.4: A CAT-scanner has its scanning array rotating around the gantry during a scan similar to what is shown when the scanner cover fails. The only part that sometimes moves when using an MRI-scanner is the patient table. See more
