When you’re a terrible and boring actor, Hollywood has a couple of tricks up its sleeve to make you more interesting. The easy one is to put a cut on your lip. A cut on a blank face shows you’re troubled by a fight without having to resort to too much acting.
Another trick, of course, is to get you to take your top off. If you’re a handsome young buck, or indeed, a comely maiden, you don’t have to do any acting at all if you’re in the nip.
This coincides nicely with the mutterings that Robert Pattinson and Kristen Stewart want more sex scenes in the films they make, meaning that the fapping tweens might not be able to watch their films anymore because they’re suddenly R rated or something.
