Richard "dike" Mantis: My quintessential noir alcohol driven private eye would be played by http://jwayne.com/wp-content/uploads/2009/12/RobertMitchum.jpg or http://4.bp.blogspot.com/_7ad6KBAXacA/SpDLCnDnsrI/AAAAAAAACIg/jiFW3au37ow/s400/Sterling-Hayden_The-Asphalt-Jungle.jpg
"Old Bone Tooth": The wiley hermit prospector-esque survivalist would be played by http://25.media.tumblr.com/tumblr_l7s3jmsxos1qajevqo1_400.gif doing a bad Walter Brennan impression (Think "Paint Your Wagon" grizzled Lee Marvin)
Xarnac The Conqueror AKA "The Scourge of Betelguese": My titular character is inspired by an alian http://img.listal.com/image/501370/600full-orson-welles.jpg with an orange tan (Since hes from the Betelguese System) and a blue pompadour, so naturally Orson would get the bid
And last but certainly not least Dr. Strangeglove: An eccentric scientist who strives for results, foregoing ethics and danger in the process. A neo-noir Frankenstein? Could only be none other than http://ultradebshootsback.com/comments/VINCENT_PRICE.jpg himself
