The Number 23 (2007)

Continuity mistake: When Walter is imagining himself killing his wife, the bed sheets change from silver to red momentarily after he wakes up.

Factual error: Right after Walter has the nightmare about killing his wife, he wakes up and turns around to see the alarm clock show 11:12. The clock makes a flipping sound when it switches to the next minute, just like those alarm clocks from the 1980s that have those little numbered plastic cards inside. However, it's a digital alarm clock and they do not make such sounds.

Factual error: Walter reads from his book he wrote in 1991. He mentions the Oklahoma city bombing. That didn't happen until 1995.

Trivia: In an interview, Jim Carrey admitted to being obsessed with the number twenty-three.

Walter Sparrow: I could have died there on the street, but that wouldn't have been justice. At least not the justice fathers teach their sons.

Walter Sparrow: Of course time is just a counting system... numbers with meanings attached to them.

Walter Sparrow: There's no such thing as destiny. There are only different choices. Some choices are easy, some aren't. Those are the really important ones, the ones that define us as people.

Question: Why didn't Walter go to prison after he confessed everything?

Question: Why did Agatha pick the book off the shelf in the bookstore over other books?
