Babyface

I have to agree with Daernoult (above), the stand-out scene in this movie is the Paul Thomas/Desiree West (aka Patricia Lee) scene, and its continuation when Amber Hunt joins in. One of the hottest scenes in all porn IMO. It really helps the eroticism of this scene that the underrated Desiree West could REALLY act (for my money porn's best actress). You have to see it to understand why, for once, good acting is important here. Note: you have to see the uncut version - which is available - the "contentious" dialogue in this scene is cut in at least one DVD release.

The notorious Kristine Heller gang-bang scene is also fantastic and runs the above a close second. In fact all but a couple of the sex scenes are really hot (and there's loads of them!).

The acting is mostly pretty good, though I have to disagree with the guy who singled out Joey Silvera and Sandy Pinney for special praise: Silvera's acting is mostly poor and Pinney's not much better, though both are good performers when it comes to the stuff that matters.

Filthy, funny and hugely entertaining, this is a well made, humorous, slightly subversive movie from the days when porn was a semi outlaw, counter-cultural activity in (mostly) San Francisco. Within a few years porn relocated itself to LA and became plastic and air-headed. Ah well...

See this movie if you want to find out just how inventive and exciting 70s porn could be at its best.
