2 Works in Limitless (2011)
After feeling that Judy has replaced him with Jack, Nick is offered a drug that allows him to utilise all of his brain in order to try and prove himself. But with a limited supply of pills Nick must be careful to not become addicted as well as ensuring that the ZPD don't find out about what he is doing. (There will be blood, violence and swearing. You have been warned)
NZT gives him more than knowledge but also takes so much.
