Corrected entry: If the team have only 9 days to complete the job then why are they always taking breaks?
Correction: This isn't a plot hole, the breaks are an intentional aspect of the movie. The men are stressed, more focused on other things (Mike) or don't really care about the job and disappear as soon as there's another option. (Phil).
Corrected entry: In the scene where Hank discovers the "treasure" in the crematorium, he finds several objects wrapped in small bags or with paper labels on them. Considering all the objects are items of jewellery or other personal effects from people who've been cremated, these tags and bags should have been burnt to ash, much like the ash that spills out as he searches.
Correction: This is not a mistake, as mentioned in the director's commentary, they say its not a crematorium where the items are hidden. It is in fact a heating vent that somebody who worked in the morgue had used to hide these items away in, therefore they would not have burned at all.
