Well unless you've known this man for some time before him asking you out I would absolutely recommend not going to his house for a first date. As for movies go with James Bond Casino Royale. It's entertaining and it doesn't have too much sex but just enough to liven things up.
It depends on whether you plan to watch the whole movie. If it's your true intention to have sex, then watch something boring. That way, it'll put you in the mood. Because isn't that the reason the guy is inviting you over to his place? I'm sure it's not "just" to watch a movie.
