A lot of us wonder why most SF films - and really films in general - are so weak. For those of you not in the know, the way movies usually are born is thusly:
1) someone gets an idea - in the shower, on the can, in a drunken brawl which may or may not involve a public restroom, or, if you're Joss Whedon, in the dorm, with a bong in your hand, watching a Friday The 13th movie, down the hall from a bathroom. The point here is this: Nearly all successful ideas involve bathrooms in some ways. Unless you're George Michael, or my old High School lit teacher, obviously. Yikes!
