The Girl Next Door is actually a very romantic comedy from 2004, despite it's porn-ish premise. It is a reference to the girl all teenage boys wished lived next door. A seriously hot girl. That looks like Elisha Cuthbert.
She's the girl next door in the literal sense for Matt Kidman, who immediately loves her. She's also the star of "The Girl Next Door." It's Elisha Cuthbert!
Eli: Matthew, I tell you that you're going to regret this. What would JFK do? You know he'd tap that ass. Matthew: Eli, you're never going to see her again. Eli: Oh, you know what? Fine! Matthew: Fine! Eli: Fine! Goddammit Matt! I swear to God if you don't fuck her, I'll kill myself! Matt! Please! Please! Matt! Fuck her for me! For me!
