On the set of Limitless, the showy series that uses a designer drug to ask 'Why not?'
Brian Finch is high. Not high high, but NZT-high, as in wired-into-every-memory-and-experience-and-morsel-of-knowledge-he’s-ever-learned high, because that’s what NZT, the designer drug at the center of CBS’ new action thriller, does: It gives normal guys like Brian the temporary ability to do anything, once he quickly calculates how to do it. He can outrun police in the middle of a crowded square. He can leap, parkour-style, down a building’s fire escapes.
