The dramatic suspense thriller “Shutter Island,” hit theaters this weekend, after months of anticipation for legendary filmmaker Martin Scorsese’s latest project.

It is a rarity for a movie to have both a superb cast leading an intricate storyline and an ingenious director to put it all together, but “Shutter Island” does.

The main character’s complex storyline  could have easily gone wrong and could have confused viewers, yet it worked.

The movie follows U.S. Marshal Teddy Daniels, played by Leonardo DiCaprio, and his newly assigned partner, Marshal Chuck Aule, played by Mark Ruffalo, as they investigate the disappearance of a murderess whom escapes from a hospital for the criminally insane in 1954.

The hospital is located on a remote costal area known as Shutter Island. A terrible storm strands Daniels and Aule on the island as they continue to search for the truth behind the supposed disappearance of the murderess patient.

Right from the start, “Shutter Island” pulls the audience in, from the introduction of Daniel’s mysterious new partner to the overall eerie presence of Shutter Island and its inhabitants.

Once on the island, the marshals find things are a lot more complicated than they appear to be. One of the marshals begins questioning the doctors, his partner and his own sanity.

From the trailer, it is obvious that everything is not as it seems in the hospital nor with the lead protagonist. Yet, Scorsese keeps the audience wondering exactly what is going to happen next.

The audience finds themself questioning what the truth is and what secrets are lurking on Shutter Island. It becomes increasingly  clearer throughout the film that Daniels is a rat trapped in  a cage, becoming more and more paranoid as he tries to uncover the truth, while also attempting to escape the island.

Leonardo DiCaprio perfectly plays the role of Teddy Daniels as the audience watches him go from a controlled and determined, authoritative figure to  a man over-stressed, fatigued and growing more insane.

DiCaprio looks the part of a man plagued by horrific nightmares of a past he is trying desperately to forget.

At times, the 138-minute movie. However, it still manages to hold the audience’s attention.

According to Variety, the film has grossed an estimated $40 million in its weekend debut, making Scorsese and DiCaprio’s fourth collaboration yet another success.

Award-winning Director, Martin Scorsese does a phenomenal job of portraying the era in which the movie is set. From the character’s vernacular and Bostonian accents to the film’s score and the inhumane theories behind psychological treatment for the mentally disturbed the movie is a psychological suspense thriller that will keep the audience wanting more.

“Shutter Island” is a beautifully constructed film about the fine line between sanity and insanity that should not be missed.
