What are the odds of both Sally Field and Robin Williams going through divorce at the same time?
Who would have guessed that this wouldn't pan out for Robin Williams? By the same token it's kind of an odd coincidence that this movie centers on the concept of divorce and adjustment and the two main characters plus director had to start all over again by the same token, I think it was nice to throw the kids of divorced parents a bone, and let them know that divorce isn't the end of the world.
BTW, there might be someone else on the cast/crew going through divorce in real life and tending their kids as well.
