The film “Limitless” begins with struggling fiction writer Eddie Morra (Bradley Cooper) having a chance encounter with Vernon (Johnny Whitworth), his former brother-in-law and a onetime coke dealer who now claims to be a pharmaceutical consultant. Wanting to help Eddie with his writer’s block, Vernon gives him a sample unregulated drug called NZT, which allows its users to take advantage of 100 percent of their brain. Popping the pill, Eddie goes from average Joe to Good Will Hunting in thirty seconds, finishing his novel and then setting his sights on amassing a great fortune in the stock market, a meteoric rise that puts him on the radar of Carl Van Loon (Robert De Niro), a titan of the energy industry who wants to utilize Eddie’s genius thinking to aid in a very difficult merger with another industry giant. Along the way, Eddie must smooth things over with his on-again/off-again girlfriend Lindy (Abbie Cornish), deal with Gennady (Andrew Howard) the Russian gangster who provided him with start-up capital for his fortune, and figure out he’s going to get his next fix of NZT when his supply starts running low.
