Corrected entry: While explaining the zombies, Red Queen says that human hair and nails continue to grow after death. This isn't true. What actually happens is that the skin dries out and shrivels away, making it appear that hair and nails are getting longer. (00:58:30)
Corrected entry: Why didn't Umbrella's higher ups just ask Red Queen what happened before sending in an assault team? She could have told them the T-virus was released and the hive would have stayed sealed. Instead, they just assumed she was nuts and sent in people to shut her down! Had even one of them said, "What happened?", the zombies would have never been released - it's a plot hammer that contradicts the whole point of having an AI run the hive. There should have been a line that said something like "All attempts to communicate with Red Queen so far have failed. The whole point of an AI that has the capability to seal the Hive is to keep the virus from escaping! Her refusal to communcate guarantees that the hive will be breached by a team that is investigating.
