Limitless (Blu-ray)

Bradley Cooper and Robert De Niro star in Limitless, a paranoia-fuelled action thriller that’ll blow your mind. Unsuccessful writer Eddie Morra’s life is transformed by NZT, a top-secret “smart drug” that allows him to use 100% of his brain and to become the perfect version of himself. But when Eddie’s enhanced abilities attract unwanted attention from the rich and powerful alike, he soon realises they’ll stop at nothing to uncover his secret. Depending on your take-away of the visual inventiveness and jam-packed plot that drives Limitless to peaks and valleys of preposterous fun, drugs are either a terrible scourge or the fundamental solution to all of life's problems. Limitless isn't exactly a morality tale, but the made-up drug that turns Eddie Morra (Bradley Cooper) from a scuzzy loser into a master of the universe does become a metaphor for ambition, menace, devastation, and ultimate success.
