If you play games with NFs it is never a good thing. You plan on asking her to double date with you and another girl right? As in, you intend to take another girl out and have her bring her BF. Well, if she does have a BF still and doesn't like you, no loss. If she does like you and does not have a BF anymore, then you've just shown her (in her eyes) that you have no feelings for her, so she'll just make up an excuse and be hurt.

And agian, the music and movie thing is almost never correct.
