Character mistake: Circus Liquor is actually located in North Hollywood, not Sun Valley (although Sun Valley is just a few short miles away from there).
Character mistake: When Sammy, the postman, arrives on the scene, he rushes up and attempts to take Vera's pulse in her neck. Unfortunately, Sammy's fingers are nowhere near the carotid artery, so he couldn't take her pulse.
Character mistake: Mr Potato Head gets torn apart by baby Molly after the opening scene. When Andy returns to the room with Buzz everyone resumes their positions, but Mr Potato Head looks for his bits and sits under the shelf with the other toys.
Character mistake: After Ryback was allegedly killed, Penn claims "we got him, but the SOB killed six men." Penn would not have known this, as he was with Dane the whole time preoccupied with Dane and his plans - he was nowhere near all the killings done by Ryback and never checked with his men at the time who was still accounted for. Also, it appears Ryback killed much more than just six by then anyway.
Character mistake: At one point Michael J. Fox says he doesn't want to end up in Danbury Correctional, why not? The Federal prison in Danbury CT would be a dream come true since he would be the only male inmate, as it became all-female in 1993.
Character mistake: While sitting on the bed, Darkly relays the story of how he got his name, saying it comes from 2 Corinthians 13:12. It, in fact, comes from 1 Corinthians 13:12. (00:10:55)
Character mistake: At the beginning, in the funeral of the young lady, the priest says in Latin the traditional "In nomine patris et filii et spiritus sancti", but he says the last word wrong, "sanctus" instead of "sancti."
Character mistake: When The Plague starts talking at the meeting and comes up with the story about a hacker planting the virus, he first says that an "unknown intruder" was the one who broke in, but only minutes later says that the cops picked up him already. (00:34:40)
Character mistake: Claudia says she is 40, her daughter is 16, it is referenced that it was a young pregnancy, however she would have been 24 when she had Kit, hardly abnormally young.
Suggested correction: 24 is still young and she doesn't say anything about being "abnormally young." Plus, in 1979, the mean age for first time mothers was around 25.5 (rising to around 28.6 in 1995), so she was on the young side of first time mothers. If she had said she was a teenager when she got pregnant, that would be a mistake.
