Character mistake: Alan Alda says that his personal security code is the street address that he lived on at Steinway Boulevard when he was a kid growing up in Astoria, NY. The name of the street in Astoria is Steinway Street. (00:19:50)
Character mistake: When travelling between zones, they go 12 - 10 - 9 - 8 - 7 - 5 - 4. Which is the only route you can take that includes zone 8 as shown. This is silly as there are quicker routes such as 12 - 7 - 5 - 4.
Character mistake: The alarm system has two codes; one (7466) that works properly and the other one (7465) that appears legit but would call the cops as well. Sarah is supposed to give the legit code, but before being cut off she says "774..." That would have not been a valid code. (00:15:20)
Character mistake: Nicolas Cage looks up the Bing results for Alan Marsh, the journalist he accidentally kind of murdered. The URL of his personal blog, hosted by the newspaper he works for, spells "blog" wrong. (00:55:25)
