Long before there was an organised PUA community this film called The Pick Up Artist and Staring Robert Downy and Molly Ringwold came out. You can watch it online for free here:

I have already seen it and it is not that great, but you can get some new tips from it. It is quite short at under 90 minutes but is worth watching if you haven't seen it before. It is perhaps better for motivation than anything else as after watching this film you will want to go out and approach.
