Continuity mistake: In the first film, George refers to the tree that the family carved their names in as being in the front yard. In the second film, this same tree is referred to as being in the backyard.
Suggested correction: It is also established he can be scatterbrained when under strain, and he is often under strain, and there's no reason they can't have two trees for that purpose.
Continuity mistake: In the first movie Annie had lived in the house since she was five, something significant enough that they wouldn't forget. In the second movie, George and Annie had played their first basketball game at the house when she was four.
Suggested correction: In the movie, when they are doing the basketball scene, George first asks Annie how many games she thinks they played out here. Then he says he remembers their first game, and it shows tiny Annie playing basketball with him on the same court. So it was at the same place.
Suggested correction: They never say where it was that she first started playing basketball. She could have very easily started playing at the age of four before they moved.
Revealing mistake: The panicked drive to the hospital ostensibly takes place during the early evening, yet there is absolutely no traffic in downtown Los Angeles.
Suggested correction: They don't live in Los Angeles, they live in San Marino.
