Continuity mistake: Ben Affleck has a large tattoo on his right shoulder/bicep that has been covered up by make-up for the movie. During the 'waterpark' scene Ben is wearing a T-shirt and when he scoops the little boy out of the water and lifts him into the air the sleeve of his shirt pulls back a little and you can clearly see the bottom of his armband tattoo.
Continuity mistake: Abby's hair colour changes between two different shades throughout the film, one much darker than the other. The most noticeable instance: In the scene where she and Ben's character make love for the first time, it changes from light to dark between his living room and the bedroom.
Continuity mistake: When Abby is about to make her "big realty deal" she has her hair in a pony tail with a piece of hair wrapped around where the rubber band would be. At first her hair is sticking up, pretty noticeably, then a couple seconds later, it's perfect and not sticking up, then sticking up again.
Buddy Amaral: Your company. The pleasure of your company. I want your input on video rentals. I stand there for hours, I can't pick anything out. I want someone to say goodnight to, a last call of the day. I don't have a last call of the day. Do you?
Donna: But if you can't forgive him, you can't.
Abby: It's not that I can't forgive him. Do you know how I spent the night after he left? Trying to figure out if I was glad, that he didn't get on that plane. If I say I'm glad he's alive, I'm glad he found me that day, or if I lie, and I say I'm not, either way it feels like I'm doing something wrong to someone I... To both of them, to him and Greg. Being with him is like making a choice.
