Okay, my picks are primarily based upon VN personas as revealed in posts (since I've never been able to interact with some folks in game as they're enemies whom I cannot understand

):
I think that Valgrim should be Quentin Tarantino, the director of our film, of course

Unless he has to be an actor, in which case I'd vote Anthony Perkins
Lensar....hmm....toughie...Nicolas Cage. Sometimes the bad guy, and real intense and proud...sometimes the good guy and an absolute flirt. Regardless, he'd have to be played by someone with a wide range, and one who's fairly surrounded by scandal.
Kaelia: Winona Ryder -- looks sweet on the outside but *definitely* has a dark, naughty side

Or she could be Tori Amos and have a cameo as well as some songs on the sountrack.
Fuzzy Moogle: Bill Murray. Just damn adorable. All the time. Period. Rawr.
Alem: Oscar Wilde (he can help write the script); he's tortured and twisted. Or David Duchovny...seriously dark and perverted yet somehow lovable
Turkinolith: Johnny Depp (goes well with Kaelia and just when you think he's fairly normal

his twisted, yet intriguing and often endearing eccentricities come out).
Mei: Sharon Stone. Oh so smart and funny, and can flash a smile that would light up a room.
Caelmas: Jim Carrey. Funny, sardonic comebacks, and you either love him or hate him
still working on others
edit: for soem reason i put a lot of returns so the message took up way too much room
