What would you do if you could pop a pill that made you the ultimate version of yourself, able to make use of all the knowledge you have ever taken in?

Write a book? Conquer Wall Street? Upset Russian loan sharks?

Well, that’s what Eddie Morra (Bradley Cooper) finds himself doing in the entertaining and visually stunning Limitless.

Eddie is a down and out writer living in New York.

When his girlfriend, Lindy (Abbie Cornish) gives him back the keys to his apartment, he feels like he has finally hit rock bottom.

But then he runs into his ex-wife's successful brother who says he can make everything better with just one pill.

NZT-48 gives the people who take it the ability to use 100% of their brains as opposed to just the 20% the film tells us we use.

Suddenly, Eddie finds he has the motivation to write, he cleans his flat, cuts his hair and can draw on any information he has read.

But writing is not enough, the enhanced Eddie wants to make big bucks on Wall Street and get Lindy back.

As Eddie becomes more and more dependent on the drug he attracts the attention of a dodgy loan shark and corporate big wig Carl Van Loon (Robert De Niro) and also starts to experience the side effects when he loses his pills and realises they could kill him.

And eventually we make it back to the beginning of the film with Eddie standing on the edge of a high rise building as a group of unknown assailants try to break in through the reinforced front door of his home.

The ideas behind the film were fantastic, giving the audience the chance to imagine what they could do with Eddie's powers.

The problem I had, however, was that it was incredibly difficult to care for the characters.

Attractive and charismatic Cooper excels himself as the perfect form of Eddie with his confidence shining through, but he does just as well taking on the role of his dejected former self and is completely believable.

However, while other characters in the film are introduced, they get lost in the plot as relationships are not fully focused on.

The characters of Lindy and Melissa (Anna Friel), Eddie's ex-wife, are underused.

Sub plots are established but are not fully developed, with a murder Eddie is accused of seeming to get forgotten before the end of the feature.

But despite this the premise does keep you entertained.

The visual effects are amazing as enhanced Eddie experiences the world around him with a new sense of brilliance.

The colours are brighter and everything is more vibrant, and the drug-fuelled fast-paced imagery gives the films a fantastic sense of extra energy and added movement.

With the evident plot holes, the film is limited rather than limitless, although on the whole it provides an enjoyable 104 minutes of entertainment for an evening in.

Rating: 3/5
