Continuity mistake: In one of the final scenes of the movie, George Lopez and his wife are depicted on swings with two red wines placed on a table. The scene transitions into another couple and later George Lopez and his wife are shown again. This time they toast and drink the wine on their swings. However, in this scene the wine they are drinking is white.
Continuity mistake: In one of the earlier scenes just after Julia has got out of bed and is telling Harrison what Valentines Day is like for women, the bathroom door behind her is shut in one shot but in the next one it is wide open as she walks towards it.
