Continuity mistake: Near the end, Jake hides in a dog crate. The dog runs out of the plane, and the baggage guys chase after it. While this is happening, a bag is coming down the conveyor belt. Between the first shot and the next angle, the bag jumps backwards.
Factual error: Eddie drops Jake off near Madison, Wisconsin after he realises Jake just wants Allie back. Minutes before this, the background in the vehicle shots shown is in the mountains. Wisconsin, especially that part of the state, doesn't have mountains. Nearly the entire film was shot in British Columbia.
