Revealing mistake: Robin Williams is working on Bannister's rememory, scanning newspaper articles. Under the first headline, "Bannister Eyes Future," the copy reads, "Whoever wrote these headlines had as much fun as I did setting them in type and formatting them into newspaper articles. But then, this sort of headline appears in the paper regularly, so maybe we all just want to have fun. Fun: such a precious commodity these days."
Continuity mistake: When Alan Hakman talks to the young girl Isabel and she gives her speech about how great her dad is, she is looking directly at him. At the end, when Fletcher is viewing the scene through Alan's eyes, Isabel gives the entire speech while looking down at the floor.
Deliberate mistake: In the last shot of the movie, Alan Hackman looks at himself in a mirror through his own eyes. But when he looks away and runs off, the camera keeps watching the empty mirror in stead of watching what he sees. (01:26:25)
Revealing mistake: Alan is watching his memories at the end after he figures out Louis didn't die; as young Alan is running out of the abandoned place you see the metal where he originally wrote his name in the beginning, but it was blank, the name Alan wasn't there. (01:18:07)
Other mistake: When Robin Williams starts to download Banister's life files the computer says there are 544,628 hours of footage (approx 62 years) yet shortly after a newspaper headline states that Banister died aged 54.
Answer: The movie provides no answer as to why the device was named "ZOE." However, one should note the word "Zoe" is actually a greek word for "life." Since the ZOE implant records someone's life, this sounds like the most logical answer to why it was named ZOE. On a side note: The first device to display moving images was called the "Zoetrope", the similar name could have had further influence as to why this implant was named ZOE.
