Morra, Bradley Cooper's character's last name, is the imperative of "to die" in Portuguese, which means the name of the character is something like "Edward Dies" or "Edward Die!".
At the end of the movie when Eddie is talking with Van Loon, it is clearly daytime. However, the shot immediately following Eddie closing Van Loon's car door where Eddie begins walking away to his "lunch, it is obviously nighttime in the background. All the street lights are on and there is a dark sky in the background.
When Gennady and his hit-men try to break into Eddie's apartment, the metal door has no marks on it. In the next scene where they cut out the lock, a gunshot is visible to the right hand side. Once inside, the door has no marks. After killing Gennady and pushing the needle into one of the hit-man's eye, the other starts firing at Eddie causing the bullet hole in the door from the earlier scene.
Eddie Morra: What was this drug? I couldn't stay messy on it, I hadn't had a cigarette in six hours, hadn't eaten, so... abstemious and tidy? What was this? A drug for people who wanted to be more anal retentive?
Yes and no. Some of the effects of NZT, like increased productivity and focus or the feeling of having to keep moving forward is similar to the effects of Adderall and Ritalin. There also seems to be a new drug called Focalin XR that can help people with focusing and efficiency too. However, the ability to recall all the memories in your subconscious and/or the ability to process information in the almost superhuman capacity that NZT provides is not an effect of any known drug.
