I'm going to give you an important insight I learned a loooooong time ago, and it's one of the few things I learned from women that actually proved to be helpful:
EVERY GIRL KNOWS THAT "MOVIE NIGHT AT THE APARTMENT" IS CODE FOR SEX.
Anytime a woman gets an invite from a guy where he says "Hey, come over to my place for dinner and a movie," they know it's code for sex, albeit indirectly. However, women are great at hearing this indirect speak and knowing what it really means. Why is this important to realize?
BECAUSE IF A WOMAN SAYS "YES" TO YOUR INVITATION, IT MEANS SHE'S ALREADY SAYING "YES" TO THE IDEA OF HAVING SEX WITH YOU.
All you have to do is (a) set the right mood, and (b) pick the right movie.
(a) Set the right mood: cook a good-smelling meal, and make sure you have something with chocolate, like baked brownies, chocolate chip cookies or some chocolate candy. Why? It's an aphrodisiac that will make her horny. Also, keep the lights dim - in dark light the eyes' pupils dilate, which makes a person look more attractive.
(b) Pick the right movie: most guys think you need to be watching some kind of romance movie to get her in the mood. NOT CORRECT. These movies just make them think about what they currently don't have, and because they'll end up being so involved in the story they may end up forgetting about you altogether.
The best results I've gotten on these home movie dates were ones where I was watching either a comedy or an action movie. Real talk, I took a girl down while watching World War Z on my desktop computer; another time, it was during the movie "Gangster Squad." You want to find a movie that will either get her laughing so she'll feel happy, or a movie that she'll only be half-interested in watching - in both cases, these things will allow you to transition into sex much easier.
Speaking of transitioning: you don't want to just go for the sex right away. Everything should be transitional movements that lead you into sex. For example: at the start of the movie you may be sitting on the couch eating popcorn or something, but you don't cuddle up just yet. You watch the movie for about 10 minutes then get up to get you and her something to drink. You sit back down, take some sips from the drink, then place your glass down and move your arm back until you have it around her. Now you're cuddled up. A few minutes later, you say something to her while leaning into her ear. Then you lean back. A few minutes later, you comment on a fragrant smell (hopefully her perfume) and smell her neck. The act of smelling is very arousing to a woman - get your nose just close enough to her neck to lightly touch it, then tell her it smells good... then lean back. A few minutes later you get back up, and go to the bathroom or something, then come back and put your arms back around her.
A few minutes later, turn and look at her.. but don't say anything. Look at her for a few seconds until she looks at you, then turn away. She'll probably ask "What, what is it?" You say "eh, nothing." She'll probably go "no, what is it" jokingly? Then say something like "eh, nothing - just thinking about much I'm enjoying this evening so far." Her: "Oh really?" Then you go "yeah... I mean, this movie is fan-tastic! Oh, and the company's not bad either

" She'll probably playfully hit you or say something like "whatever, you're crazy!" in a playful way. Start playfully tickling her back or hitting her with a pillow in a flirtly way... and at that point, I'm usually starting to kiss them, first on her neck, then I move to their mouth and... well, you get the idea.
But yea... remember, she already said yes to coming over for a "movie," so don't think doesn't know what should be going down. Hope this helps!
