Goofs

After Samantha offers Nick Valium for his withdrawal symptoms, the yellow kayak (which we saw Nick drag to the far side of the yard in an earlier scene) appears behind her in the vicinity of the improvised living room. The kayak has been moved there to be revealed as the location where Samantha has hidden his beer. In the morning when he awakens from his stupor the kayak is back in place near Elliot and Kitty's yard, where Nick originally dragged it.

A towel on the back of the chair behind Will Ferrell slips down and is pulled back up behind him during his conversation with Rebecca Hall about her husband.

The Band's "I Shall Be Released" was never the first track on any side of an album, as shown when the needle drops on the outer edge. It was the last track on 1968s "Music from Big Pink".

There are at least two legal issues that the movie takes liberties with. The first is the fact that, as the owner of the house, Nick's wife cannot legally lock him out. The second is that Frank Garcia gives him notice that he must be off the lawn in three days, but the course of the film suggests that he remains there for up to a week.

In Nick's high school yearbook, Delilah's phone number included the area code. In the 1980s, no one would have used the area code, especially since the 602 area code was the only area code in Arizona until the mid nineties.

Some pictures (and names)in the yearbook are used multiple times, some with different cropping, others not.

Camera and camera operator sitting motionless are reflected for an extended length of time in the glass shower door in Nick's master bathroom (lower left of frame). Scene occurs toward the end of the film, after Nick is provided keys to new locks and regains access to his home.

When we finally see inside Nick's house the master bedroom is decorated with Mrs. Halsey's 'Koi' trophies which is a very odd place for them. Since his wife has spent a small fortune on her hobby turned business, converting their swimming pool into a Koi pond and their backyard into a Koi hatchery why would she hide them in a private room like her bedroom instead of displaying them together in a public part of the house like her office, library or entrance hall where potential buyers might see the awards her successful breeding program has produced?
