Bladerunner, anything but the voiceover version, is one of my favourites, Sci-Fi or otherwise. Without agonising over it, my top SuperStu movie picks; Ghostbusters, Super Troopers, Miller's Crossing, Usual Suspects, Big Lebowski, Alien, Scarface, The Three Amigos, American Psycho, Maltese Falcon, Big Trouble In Little China, Bullitt.
Stuff I avoid includes; anything by John Woo, Ryan Reynolds, Spielberg since Jaws, all remakes except The Magnificent Seven, comic book movies except Batman, Tom Cruise after Top Gun.
My all time favourite movie is probably Raising Arizona. I'll watch anything with Olivia Wilde or Monica Bellucci in, regardless of my principles which might conflict with the film's genre.
I absolutely love movies, one day I'm going to make a film noir. Script is work in progress.
