LIMITLESS takes its title from the idea of how many opportunities are available to us if we were able to use 100% of our brains instead of the mythological 20% that we use in our everyday lives.

However, scientists say that we already use 100% of our brains, and so the premise of the movie needs a better explanation.

Bradley Cooper plays Eddie Morra, a writer with a book contract, but he looks more like someone with an alcohol or drug problem.

That might be because he doesn’t act like a writer, either, because he is behind on his book, having written only one word, and that word is the first-person, singular pronoun “I.”

Limitless MovieEddie gets even more down on his luck when his girlfriend Lindy breaks up with him, but then his life changes dramatically when he accidentally meets the brother of his ex-wife on the street.

Vernon tells Eddie that he is working for a company that has come out with a new pill called NZT48 that lets you access 100% of your brain, but then he gets interrupted by a phone call and has to leave.

However, Vernon gives Eddie his business card and one of the NZT pills “on the house,” saying that they normally cost $800 apiece.

And the rest, as they say, is this movie.

Special effects show an impression of what happens to Eddie when he takes the pill. “I wasn’t ‘high,’ I was just clear,” he tells us in voice-over narration. “I knew what I wanted to do and how to do it.”

And he does. The next morning, the effects of the pill have worn off, and Eddie gives his book manuscript to his publisher, saying that if she doesn’t like it, he will return the advance.

Then when Vernon doesn’t return Eddie’s calls, Eddie goes to see Vernon with the objective of getting more pills.

And here is where the movie starts leaving the audience with unanswered questions.

Here is also where more characters enter the story, including a Russian loan shark and his hooligans, a financial businessman played by Robert De Niro, a mysterious man who seems to be following Eddie around New York City, and even Eddie’s ex-wife, Melissa.

LIMITLESS makes a thriller out of limitless opportunities, but it is more like “overblown” with unanswered questions.
