Contagion (2011)

Character mistake: During the interview with Dr. Sanjay Gupta, Alan Krumwiede incorrectly describes what an R naught of 2 means. He claims on Day 1 there were 2 people infected, then 4, then 16, then 256... This is raising each number to the 2nd power (squaring each number.) But we learned earlier in the movie from Dr. Erin Mears that the R naught indicates the number of people who will become infected by 1 infected person. So to calculate the spread of the disease, each # of infected should be multiplied by 2, not squared. It should go Day 1 = 2, Day 2 = 4, Day 3 = 8, Day 4 = 16, Day 5 = 32, etc. (01:06:35)

Dr. Ellis Cheever: What have you eaten? I mean something that didn't come from a vending machine.
Dr. Erin Mears: Taco Bell!

Trivia: Contagion got various accolades for its authenticity, being "very well fact checked compared to most science blockbusters", according to New Scientist. The screenwriter did months of research, enlisting the help of epidemiologists who edited the script and guided the actors.

Question: After Alan Krumweide starts spreading misinformation about Forsythia curing MEV-1, we see a scene in a pharmacy being flooded with desperate customers. But if Forsythia is a homeopathic drug, then why is it being sold in pharmacies in the first place? As the characters say later on, it takes months just to get a drug approved, let alone sold.
