Thanks to an all-too-brief, and startlingly creepy performance in The Purge, Australian former soap star Rhys Wakefield has seen his face become the instantly recognisable motif of that movie. And while that movie wasn't universally loved, its strong points - the concept and the villain - were excellent, and made the less well executed moments easier to accept. In The Purge, Wakefield was psychosis personified, the kind of well-mannered, smiling psychopath who is probably distantly related to Hannibal Lecter and Patrick Bateman. He was a glorious grotesque, a caricature whose face and presentation were almost enough to cement the immediate mythology of the character before he even spoke or committed any act of villainy. That is precisely the kind of impact that a lesser character would need, and the image of Wakefield calmly stalking around Gotham in the same manner as his measured, brutally sadistic walk around Ethan Hawke's house in The Purge would be immediately iconic. Though Gotham could go for misdirection and cast someone who isn't obviously going to turn into the Joker, there is certainly something to be said about the idea of him already being a psychopath before his transformation, which leads nicely to the top fantasy pick...
