She's Out of My League (2010)

Continuity mistake: The scene in Molly's apartment when she's pouring wine and the dog is barking, there's a shot of Molly with both glasses full telling Kirk to sit down, then a shot of Kirk asking who should sit, him or the dog, then a shot of Molly pouring the 2nd glass. (00:48:10)

Kirk: Stainer, I know you don't like her very much.
Stainer: Nooo, no. I hate her. In fact, the day you broke up with her I marked that down on my calendar as a day of rejoicement. I'm going to celebrate it with a cake with her face on it, but instead of eating it, we smash it.

Trivia: Prior to their first date, Molly, her sister, and Patty are shopping. The sister holds up a dress, and the consensus is that it is horrible. When Molly and Kirk go to visit his family, Marnie is wearing that very same dress.
