Corrected entry: Cowan disappears from the truck from when Fuller shows the video to when the truck is backing up for placement. He wouldn't have gotten out of the truck as he wouldn't want the Horsemen to know it was being staked out. He couldn't be on the side of the safe as he wouldn't fit on either side.
Corrected entry: When the FBI find out that the safe isn't in the warehouse, Cowan shouts to one of the curators "You tell me what's going on right now because this is bullshit!" and Evans then begins pretending to play a violin ("Bullshit" being the trigger word) revealing that he was hypnotized by the Four Horsemen just like the French banker. However, when they were on the bridge prior to this, Cowan says "Despite their bullshit Robin Hood razzle-dazzle, your magicians are nothing more than common thieves" with Evans in their presence when he said this. If "Bullshit" was the trigger word and Evans was hypnotized, shouldn't Evans have begun to pretend to play the violin then?
Corrected entry: The point of the New Orleans show was revealed to make Tressler broke and give the audience the money Tressler owed them. However, this plan would have had parts which were out of their reach. For example, the Fifth Horseman could have gotten the names of the people insured by Tressler Insurance. But the Four Horsemen or Fifth Horseman would have had no way of knowing that those particular people would have come to the show, nor would they have known that every single person in the audience was insured by Tressler Insurance.
