If it was a biopic about Glenn Greenwald, I would have immersed myself more fully in his personal life and gotten to know him as much as I could, but because it was much more about his relationship to this particular situation, to The Guardian, to Laura Poitras, and to Ewen MacAskill, and Edward Snowden, I was able to really learn a lot about him from reading his book and reading his many articles and accounts of that time.
