'Shutter Island' is a Clayton's Scorsese film that has an inherent problem with its casting. I kept thinking to myself that had Scorsese used a more imaginative approach to casting his main character, played by Leonardo di Caprio, the film would have been more credible and the plot twists more exciting. As well, some of the production design is darn shonky and the paintwork on the stone walls of the main location very fake looking, as are all the . All this detracts from what could have been an 'edge of the seat' thriller. The performances are not bad, it's just that they are wrong for this kind of story, or cliché, such as Max von Sydow.
This is a story about inmates of an asylum, set on an escape-proof island and full of grey stone and dreary lighting. The performances are competent but there are also some lines that completely grate and pull the story into melodrama.
Go along and see it though, if you have time and a bit of cash, as you won't be bored. There is plenty to involve you for the most part and cinema tickets are good value compared with other forms of entertainment. It's just that it is disappointing to see yet another book adaptation that doesn't work.
I am thinking that the only adaptation I have ever seen that DID work was 'War and Peace' in 1967 (Dir.: Bondarchuk).
