Obviously the crate is meant to be the same as the one in which the government’s “top men” squirreled away the Ark of the Covenant in an enormous warehouse at the end of the first film.
Only look: the number on the crate in the new picture is 9906573. Could I have been the only one to notice immediately that this does not match the number on the crate in the first film, 9906753?
No, I know one more person who immediately spotted the (apparent) error: my equally film-geeky sister Suzanne.
