Continuity mistake: In the scene near the end of the movie where Peter apologizes to Joanna, Joanna is shown either in her red shirt and holding her blue jacket, or wearing her blue jacket. For instance, as Joanna is moving in to kiss Peter, she is holding the jacket, but as they embrace, she is wearing it. In the blue jacket cuts, it is much less windy, and Joanna's hair is styled differently than it is in the red shirt cuts, where her hair is blowing due to the wind.
Continuity mistake: During Tom's BBQ when Michael Bolton and Samir are asking Tom's lawyer about prison you see Michael lose grip and drop his cup with a piece of ice hitting Samir in the head. When the ice hits him he's holding the cup in his left hand but when the camera angle changes the cup shows up in his right hand.
Peter Gibbons: What would you do if you had a million dollars?
Lawrence: I'll tell you what I'd do, man, two chicks at the same time, man.
Peter Gibbons: That's it? If you had a million dollars, you'd do two chicks at the same time?
Lawrence: Damn straight. I always wanted to do that, man. And I think if I had a million dollars I could hook that up, cause chicks dig a dude with money.
Peter Gibbons: Well, not all chicks.
Lawrence: Well the kind of chicks that'd double up on a dude like me do.
Peter Gibbons: Good point.
Lawrence: Well what about you now? what would you do?
Peter Gibbons: Besides two chicks at the same time?
Lawrence: Well yeah.
Peter Gibbons: Nothing.
Lawrence: Nothing, huh?
Peter Gibbons: I'd relax, I would sit on my ass all day, I would do nothing.
Lawrence: Well you don't need a million dollars to do nothing, man. Just take a look at my cousin, he's broke, don't do shit.
Peter Gibbons: So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life.
Dr. Swanson: What about today? Is today the worst day of your life?
Peter Gibbons: Yeah.
Dr. Swanson: Wow, that's messed up.
