"My two older brothers are both molecular biologists and neuroscientists, and I feel like representing them accurately is never done in movies, and I really wanted to at least capture the spirit of a Ph.D. student whose goal and aspiration is to increase the sum total of human knowledge. That is noble. That was really, really important, to capture the three-dimensionality of scientists. Scientists fall in love, scientists have the greatest sense of humor, scientists are passionate."
