Query: "Duel" is demoniacally clever!

The first thing you have to understand about Jack Paccione is that he is a visionary--imaginative with the camera, a manic workaholic in post production, a humble, creative soul. Working with Jack is a pleasure.Sean Walsh and Eddie Fontana have great chemistry together--they make great foes! I can imagine that ping pong scene must have been a tough shoot--especially with the amount of takes necessary for editing footage.I wish you guys lots of luck! You really have a quality piece here, no matter what anyone else (with descriptive job suffixes...)has said in a review. It really looks great and moves quickly! Fantastic!
