I will get to the figuring it out part in a bit. I thought the story was a little too out there. The movie is set in 1960 and Hobbs' wife has been dead for 15 years we are told. That coincides with the end of WWII. How much medical knowledge of cancer and how many medical resources during war time are we expected to think were devoted to treating the wife of a janitor in war torn England? Michael Caine's acting is strong enough to generate sympathy for his cause and purvey his deep love for his wife. Why is Miss Quinn(Demi) speaking in a British accent? We are told twice during the movie she is an American who studied at Oxford. Now back to the figuring it out part. Do you know why we are finding it difficult? Answer: it's insane. Our janitor struggles to make it down the vault passageway for his first trip using her phone call as a distraction and dumb luck with the security man eating a crumpet at the exact right time. Remember we are talking about 4000 pounds of diamonds. How many trips do you think that would be pushing a single cart across a MARBLE floor without damaging it? I won't elaborate as to make this a spoiler but I was a little disappointed. The story was a little more than a heist flick. There was the social commentary on the health care industry, glass ceilings, and blood diamond oppression in South Africa. Maybe they were biting off a little more than they could handle in one hour and 45 minutes. Nice acting by all, I especially liked Joss Ackland(_Bill and Teds Bogus Journey, Red October_) as Sir Ashtoncroft. Give this movie a chance despite my minor rants here, it is a decent watch.
