1. Predator - I feel this is as perfect as an action movie can get. John McT has two of the best evers in his filmography with this and Die Hard. Also, I like to think of this movie as a sort of prequel of sorts to Commando, in my own dream world.
2. Commando - maybe it didnt give birth to the modern action film, but it sure gave birth to the Modern Arnold Film. One liners, over the top violence, high body count. Amazing movie.
3. Conan the Barbarian - Just an awesome piece of film. Milius had a great script. Arnold was born to play this role.
4. T2 - 4th may seem low, but i love the hell out of this movie. It is very awesome. I knocked it down a bit because Arnold is ordered to keep the body count low, sort of took the fun out of it a bit, but still a landmark movie.
5. True Lies - Awesome Awesome Awesome movie. Great arnold-isms. One of the best ever was the interrogation scene..."You know my handcuffs...I picked them" Jamie lee curtis annoys the hell outta me in this movie though.
6. Total Recall - God, this list is so difficult to make, I dont like putting this movie so low cuz it kicks ass. Great Phillip k. Dick story, great direction by verhoven. Arnold's sci-fi opus.
7. Twins - His best comedy EVER. I think it still holds up very well. Great chemistry between DeVito and Arnold. "YOu are forgetting the third rule of a crisis situation"
8. Kindergarten Cop - What an awesome movie. Hilarious.
I cant go on. Eraser is pretty good, the rest of his movies are pretty crappy. Raw Deal had potential but is too low budge. Pumping iron i dont really consider a true arnold movie. Batman and robin...gross. 6th day, end of days, yadda yadda, they all sucked.
Arnold's classics are untouchable.
Oh, and john matrix would OWN Rambo.
Also, I have no clue where I would put T3. I LOVE THE HELL OUT OF THIS MOVIE. But its too early for me to place it anywhere. I do know that it is truly an Arnold Classic already. What a movie!!!
