Following Kristie and Keith's discussion about Porsches while they're at the beach, their respective dogs wrap their leashes around their owner's leg. While Kristie's dog solely wraps her leash around Kristie's legs, and Keith's dog solely wraps his leash around Keith's legs, Kristie and Keith act as if they are tied together i.e. that the two dogs wrapped the leashes around both their legs together.
When they go to the beach to find the dogs, they sit in a log and talk in what appears to be heavy winds, however the audio must be ADR because you can't hear any wind.
In the movie, Keith's colleague's name is said to be Laura Presley. In the end credits, it is listed as Laura Prescott.
Early in the movie, Dan's surname is said to be Carlisle. Later in the movie, it is said to be Givens.
