Ok, so th scenario should look like this. She comes at your home you hug her with love so that she can feel your warm, then youb should cocky&funny a little untill you play the movie. And now what ? hmm, because is a thriller movie, if she is scare she should hug you in some moments of the movie, if so, bammm !!! you got her. Because she is doing something unconscious. Try to escalate durring the movie, easy, very easy, because the movie is long and you have eenough time, to make things better. After the movie is over, i suggest you to play some games with her. Tell her to play a strip game, such as poker or dices, else you can simply suggest to watch a porn movie together.
If you have more questions, ask me. But please give me an advice for the link from the top i share you
