9. Tammy Layer Cake
Ok, so Daniel Craigs just as much to blame for this, but even if they were going to hook up, Sienna Millers Tammy probably should have told Craig about Sidney. Granted, the boy looks relatively green for a gangland murderer, but hes still clearly got access to guns and judging by his VIP privileges at a local nightclub, certainly has some sort of reputation. Yet Tammy does absolutely nothing to tell Craig about this potentially murderous baggage. Again, though you might argue that the bloke knew what he was getting into, he only met the bloke in two business situations and judging from those two meetings, he seemed a bit benign. Yet Tammy has the advantage of actually knowing him, and knowing what hes capable of. Really, it just seemed a bit dim that she didnt mention a murderous ex-boyfriend, especially when she seemed so intent to be seen out in public with her new man. And anyway, I know he technically turned down the job as kingpin of the London underworld, but hes now surely minted enough to afford some security to guard against possible armed nutjobs. Not doing so just seemed a bit dim, and put a massive downer on what was otherwise an awesome ending.
