Let's count the continuity errors...
Just for fun, I noticed these errors (other than the 2003 calendar).
1. The Alicia character is called "Lacey" in some scenes.
2. Affleck answers his cell phone with "How did you track me down?" Um - it's a cell phone, Ben. It goes where you go. Even so, there was a scene where he gave all that info to his secretary.
3. Bill Macy (DooDah) is up in the kid's room, and then his understudy is knocking at the door. Where'd Bill go? Maybe there was a "Maude" retrospective on the TV.
4. They go tobogganing for an afternoon and wind up in the Rocky Mountains. It sure ain't Chicago.
5. They wind up with colds after tobogganing that vanish by the next day.
I'll bet there's more - anyone else what to jump in, or is this just piling on a bad film?
