Casting my own porn movie...
I decide whether to cast him as a top or a bottom (he's probably versatile). His look will determine whether I'm going to put him in leathers, or maybe a jock strap, or sexiest of all, just completely naked. If he's really fit and has a nice face he might make it onto the cover, but it depends on who I might see later in the day. Maybe I'd put him in a scene with that other guy I saw standing at that bus stop earlier. Or maybe I'd save him for the last scene which is always with me.
