Ah, movies. A fav topic of mine
Memento -- A movie where at the beginning you know exactly what is going on, and at the end you haven't a clue what's real and what is the guy's imagination

Aliens -- Excellent sequel. Bunch of kick-@$$ marines vs large, nasty bugs.
Ginger Snaps -- Werewolf movie combined with female coming of age. No real 'classic' heros, shows the underbelly of modern highschools, interesting ideas about trying to deal with turning into a humanoid wolf over the course of a month. And and ending that bucks all the trends in mondern movies!
Kevin Smith movies -- (Clerks, Mallrats, Chasing Amy, Dogma, Jay & Slient Bob Strike Back). All excellent movies, IMO, usually with unique commentary on society. Chasing Amy is one of the more unconventional romantic comedies to come along in ages. Dogma is my fav, and a GREAT take on religion (note, it's religion, not God).
Charade -- An older movie, here. Audrey Hepburn & Cary Grant. An excellent murder mystery, conatins some excellent twists and probably some of the greatest one-liners between the stars in any movie I've ever seen
Idle Hands -- A total slacker gets his hand possessed by a demon and ends up killing people. Dark slapstick comedy. I LOVE the part where he fights the hard for control of the remote control. As a bonus, you get to see Seth Green killed (Though it dosen't take). Nice preformance by The Offspring, too.
The Whole Nine Yards --
NOT a football movie! Ex-hitman Bruce Willis movies in next to dentist Mathew Perry. And Perry's golddigging wife convinces him to rat out Willis to the mob for a reward. Great chemestry.
The Ninth Gate -- Johnny Depp plays the anti hero as a rather underhanded rare book dealer who is hired to research a book that can apparently summon Satan. However, he's not the only one after the book.
Ronin -- A group of mercs are contracted to retireve a mysterous box in southern France. My friend insists that there's really a pizza in the box.
Rocky Horror Picture Show -- While often filed under Horror due to its title, this movie in fact features Tim Curry as a singing, dancing, transexual, transvestite from Transalvania. If seen in its regular format, it's one of the dumbest movies ever made, if seen with the callbacks (available on the DVD, though you need a good soundsystem to make them out. Cr@ppy coordination amongst the people who made it) it's one of the most hilarious things you'll ever see.
Arsenic and Old Lace -- Carry Grant, B&W. This is one movie I think everyone should see. Grant is a poor sucker who finds his two sweet, old aunts are killing people and hiding the bodies in the basement. And just when you think things can't get worse, they DO! (Boy, do they ever). A great movie that could never be remade, and a prime example of how movies SHOULD be done.
Night of the Living Dead (1991 edition) -- The dead come back to life and society falls to pieces. LOVE the ending to this one! Also check out the comedic parody Return of the Living Dead (featuring, at one point, a nekkid chick in a grave yard).
The Long Kiss Goodnight -- Geena Davis as a woman with a deadly past and no memory of it, and Samuel L Jackson as a burnt out detective who helps her find it. Lots of action, wickidly funny at some parts.
Freaked -- A rare find, but an excellent one! A spoiled movie star, his buddy, and a female hitch hiker get suckered into a freak show and turned into attractions. Unique, very funny. I was almost on the floor when the kid/troll gets sucked out of the airplane door.... and then 'lands'.
Anyway, happy hunting!
